Monitorix configuration file

NAME

monitorix.conf - Configuration file for Monitorix.

DESCRIPTION

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used on production Linux/UNIX servers, but due to its simplicity and small size may also be used to monitor embedded devices as well.

It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Since 3.0 version Monitorix includes its own HTTP server built in, so you don't need to install any web server to use it.

Every time monitorix is started it reads the configuration file from the path specified in the command line (using the -c option), and once checked, it creates the index.html file that will act as the Monitorix main page.

It also creates a file called <base_dir>/cgi/monitorix.conf.path that includes the absolute path of the configuration file. This file will be read by monitorix.cgi to determine the exact location of the configuration file.

CONFIGURATION OPTIONS

IMPORTANT NOTE: these options have default values that might vary depending on your operating system. Please check the configuration files in /etc/monitorix/conf.d/.

Blank lines are ignored, and whitespace before and after a token or value is ignored as well as tabulators, although a value can contain whitespace within. Lines which begin with a # are considered comments and ignored.

If you want to comment out a large block you can use C-style comments. A /* signals the begin of a comment block and the */ signals the end of the comment block.

If an option has multiple values their must be separated by comma.

title

A free description of the server; where it is located, the Company name, etc.

Default value: Place a Title Here

hostname

The name of the host.

Default value:

theme_color

RRDtool comes with a default white theme, and since Monitorix introduces its own black theme, you have two predefined themes to choose from.

Default value: black

refresh_rate

The refresh rate (in seconds) of the statistics web page displayed in your browser. If set to 0, page refreshing is disabled.

Default value: 150

iface_mode

The interface mode defines the manner in which data is shown in the browser. Since version 1.4.0 it has been possible to display the graphic data using plain text tables. This allows Monitorix to be used by those running screen reader software, and also simplifies automatic data processing through scripts.

The possible values are:

graph for rendered graphs.
text for plain text representation.

Default value: graph

enable_zoom

Zoom allows double clicking any graph in order to see a larger version (zoomed in). This is especially useful for seeing additional detail.

Default value: y

netstats_in_bps

This option toggles network values between bits (bps) and Bytes (Bps) per second. By default the values will be shown in Bytes per second (Bps).

Default value: n

netstats_mode

This option toggles network visualization mode between overlapped (input and output values appear one in front the other) and separated (input values appear on top and output values below, in negative).

Default value: overlapped

disable_javascript_void

This option enables or disables the use of javascript:void-URLs when opening windows with zoomed graphs. Some people likes to open links in the background by pressing the middle mouse button in Firefox, and with the default javascript:void-URLs the only they get is an empty window with nothing in it.

Default value: n

temperature_scale

This option toggles between values in Celsius or in Fahrenheit in those graphs that represent temperatures.

The possible values are:

c for Celsius.
f for Fahrenheit.

Default value: c

show_gaps

This option, when enabled, shows the gaps (missing data) in the graphs. This is specially useful to detect if the server or Monitorix were stopped for a while, or any other unavailability.

In order to be able to locate those gaps easily in each graph, it uses the white color in the default black theme and the black color in the white theme. These default colors are defined in monitorix.conf so they can be changed as any other option.

Default value: n

global_zoom

This option zooms all the graphs (including the legend's font size) by the given amount. The factor must be greater than 0 and it accepts decimal values.

This is specially useful for people with big screens that either want to avoid using the browser feature to zoom the contents of the window and for those that watch the graphs from certain distance.

Keep in mind that the contents of the graphs remains with the same detail level all the time, and that it doesn't affects to the standard zoomed graph that appears when clicking in the picture.

Default value: 1

max_historic_years

This option defines the maximum number of years of historical data in all graphs.

WARNING: Every time this value is extended Monitorix will resize every .rrd file accordingly, removing all historical data.

There is no longer any upper limit for this value.

Default value: 1

accept_selfsigned_certs

This option forces to accept self-signed certificates when collecting values remotely using HTTPS protocol.

Default value: y

priority

Sometimes when a server is under heavy use, Monitorix might be unable to collect some statistical data due to its normal priority (0 by default). This makes monitoring useless because graphs are empty during that hard period of time.

In order to mitigate this situation this option sets the priority in which Monitorix will be scheduled by the kernel. The accepted range of values is the same as in the setpriority() system call: that is, from -20 (maximum priority) to 19 (lowest priority).

Default value: 0

image_format

This is the format of each generated graph. There are only two possible values: PNG and SVG.

Default value: PNG

enable_parallelizing

This option will fork an independent process for each graph in order to speed up graph generation in multi-core systems. It's best to keep it disabled on unicore processors.

Default value: y

enable_rrd_lock

This option will synchronise the rrd file access by creating the file /tmp/monitorix.lock and use it via flock. The read lock during the cgi call can be disabled on a per call basis via setting the environment variable INHIBIT_LOCKING. This is useful for modules that call the cgi function internally.

Default value: n

enable_relative_urls

This option will change all URLs in the graphs to relative, instead of absolute URLs.

Default value: n

include_dir

The main configuration file is usually called monitorix.conf and its location is provided as part of the command line arguments. In addition, other configuration files may be loaded placing them in the directory pointed by this option. The names must end with .conf to be included.

This option is mainly intended to include third-party modules with their own configuration files without having to modify any file from your Monitorix installation. All modules are located in /usr/lib/monitorix (in some operating systems that path can change).

All the configuration files in there will be loaded in alphabetic order, so the last file loaded will overwrite any previous option.

Default value: /etc/monitorix/conf.d

additional_graph_name

This is an optional configuration option for configuration files in include_dir. It takes a comma separated list of additional modules that is appended to the graph_name option. This enables you to add custom modules without changing the monitorix.conf or copy all names from graph_name to your config file.

Default value: None

ip_default_table

This option will define in which table Monitorix will put all iptables rules for network traffic accounting monitoring. It only works on Linux.

Although this is a global option, only the graphs port, nginx and traffacct are affected by it.

Default value: filter

ipv6_disabled

This option enables or disables the use of the ip6tables command. It only works on Linux.

Although this is a global option, only the graph port is currently affected by it.

Default value: n

url_prefix_proxy

This option forces monitorix.cgi to bypass the URL building. This is specially useful when Monitorix is used behind a reverse proxy.

An example would be: http://myexternalwebsite.com

Default value:

enable_hourly_view

This option enables or disables the ability to select the hourly view in the main page.

No .rrd file will change by selecting this option and the historical data won't be affected.

Default value: n

user_agent_id

This option defines the string to be used to identify Monitorix in the HTTP requests. Its value will be sent as the "User-Agent" header.

The default value will depend on the current Perl version in your system. An example would be libwww-perl/5.833.

enable_back_button

This option enables or disables the ability to go back to the main page from the graphs page without using the browser's back button.

It will show a back arrow in the upper-left corner and it is specially useful for people using the browser in full-screen mode.

Default value: n

rrdtool_extra_options

This option permits create a comma-separated list of RRDtool options that will be included in all graphs. This is specially useful if you want to take advantage of an specific RRDtool graphics option.

An example would be:

rrdtool_extra_options = "--grid-dash=1:0, --no-legend"

use_external_firewall

By default, Monitorix creates a set of iptables rules to collect the amount of network activity that some graphs (port.pm and nginx.pm) need. This might be a problem for people using an external firewall that could eventually remove such iptables rules created by Monitorix. In these cases, you may want to set this option as y to tell Monitorix to not create such iptables rules, but expect that they will be already created by an external software.

Keep in mind that the rule names created in your firewall must coincide with the names that Monitorix expects to find for each case. Familiarize yourself with the iptables rules created automatically by Monitorix before enabling this option.

Default value: n

base_dir

This is the absolute path to the directory where all the web elements are located:

cgi/ directory where resides monitorix.cgi.
imgs/ directory for the .png graph images.
index.html Monitorix main page.
logo_bot.png Monitorix bottom logo.
logo_top.png Monitorix top logo.
monitorixico.png Monitorix favicon logo.

Default value: /var/lib/monitorix/www/
(depends on the operating system)

base_lib

This is the absolute path to the directory where all of the monthly reports, daily traffic usage, and RRD files are located:

reports/ monthly reports localization directory.
usage/ daily traffic usage data directory.
*.rrd RRD files.

Default value: /var/lib/monitorix/
(depends on the operating system)

base_url

This is the URL prefix that Monitorix utilizes when referring to its own pages and files.

Default value: /monitorix

base_cgi

This is the URL prefix that Monitorix utilizes when referring to monitorix.cgi.

Default value: /monitorix-cgi

HTTP built-in server

enabled

This enables or disables the HTTP server that Monitorix has built-in. This is specially useful for system administrators that don't want to install a web server (Apache, Lighttpd, Nginx, etc.) to see the Monitorix graphs.

Default value: y

host

This option takes an optional host address for this server to bind to. If none is specified (default) it will bind to all interfaces.

Default value:

port

This is the network port from where the HTTP server will listen on.

Default value: 8080

user/group

This sets the user and group that the HTTP server will run as.

Default value for user: nobody
Default value for group: nobody

log_file

This is the path to the HTTP server log file.

If you leave this option blank or undefined Monitorix will log using the standard file descriptors. This is specially useful on systemd-based systems, you'll need to use the command journalctl -u monitorix to see the logs.

Default value: /var/log/monitorix-httpd

hosts_deny

This is a comma delimited set of IP addresses which are not permitted to access Monitorix graphs. There is the special keyword called all that can be used to deny all IP addresses.

The access control uses the same approach as in the TCP-Wrappers; the search stops at the first match:

- Access will be granted when an IP address matches an entry in the hosts_allow list.
- Otherwise, access will be denied when an IP address matches an entry in the hosts_deny list.
- Otherwise, access will be granted.

Default value:

hosts_allow

This is the opposite of hosts_deny option. IP addresses listed here are permitted to access Monitorix graphs. There is also the special keyword called all that can be used to allow access to all IP addresses.

Default value:

https_url

This will force to use the prefix https:// in all links. This is special useful if you plan to use a reverse-proxy HTTPS server in front of the Monitorix HTTP built-in server.

Default value: n

autocheck_responsiveness

There is a well known problem with the HTTP built-in server that Monitorix implements using the Perl module 'HTTP::Server::Simple'. It looks like it's pretty weak to the common attacks that any web server receives every day. As a consequence of that, it just hangs, and when you want to see the stats of your server, you just see your browser waiting for a response that never comes, which ends up with a timeout. In these cases, you are forced to login to your server and restart Monitorix, in order to refresh the HTTP built-in server.

So in order to mitigate (hopefully) all this annoying hangups, this options acts like an autocheck to control the responsiveness of the HTTP server on every minute, and in case of no response then it will be restarted automatically.

Default value: y

HTTP built-in server with access authentication

enabled

This enables or disables the authentication mechanism to control access to pages and other resources. The only allowed mechanism is Basic and uses the 401 status code and the WWW-Authenticate response header.

It's highly recommended to set this option according your needs before start Monitorix.

For more information about the Basic access authentication mechanism and its security implications, please refer to http://en.wikipedia.org/wiki/Basic_access_authentication.

Default value: n

msg

This option sets the Realm to be used in the authentication. That message should appear in the client dialog box to help user to identify the secure area.

Default value: Monitorix: Restricted access

htpasswd

This option sets the path to the password file that was created with the help of the htpasswd.pl script. That script encrypts and validates passwords using the system's crypt() routine. If your Monitorix package doesn't come with that script, you may use the similar htpasswd(1) program provided with the Apache web server.

The format of the password file consist of one or more lines with a username and password separated by a colon.

The following is an example of a password file:

paul:oGkEsQK6RYIII
peter:HF1r7qRL4Kg6E

Since the script uses the crypt() algorithm, only the first 8 characters of the password are used to form the password. If the supplied password is longer, the extra characters will be silently discarded.

WARNING: don't use the character colon ':' as part of your name or password since this character is used as field separator.

Default value: /var/lib/monitorix/htpasswd

hosts_deny

This is a comma delimited set of IP addresses which will be forced to do authentication. There is the special keyword called all that can be used to deny all IP addresses.

The access control uses a similar approach as in the TCP-Wrappers; the search stops at the first match:

Default value: all

hosts_allow

This is the opposite of hosts_deny option. IP addresses listed here will bypass the authentication mechanism (even when it is enabled). It helps in specific cases like to avoid to have to include the auth credentials in the url_prefix of the emailreports module. There is also the special keyword called all that can be used to allow access to all IP addresses.

Default value:

Log files pathnames

log_file

This is the path of the Monitorix log file. Please check this file periodically and especially after every update to confirm proper operation.

Default value: /var/log/monitorix

secure_log

This is the path to the system log (also known as auth.log, etc.) Monitorix uses this file to report SSH, POP3, FTP and Telnet successful logins.

Default value: /var/log/secure

mail_log

This is the path to the mail log file. Monitorix uses this file to report messages sent (supporting Sendmail and Postfix formats), and the MailScanner log format for spam-mail and virus-mail alerts.

Default value: /var/log/maillog

milter_gl

This is the path to the dump file of milter-greylist.

Default value: /var/milter-greylist/greylist.db

imap_log

This is the path to the IMAP (Dovecot or UW-IMAP) log file. Monitorix uses this file to report IMAP and POP3 successful logins.

Default value: /var/log/imap

hylafax_log

This is the path to the Hylafax log file. Monitorix uses this file to report successful FAX dispatches.

Default value: /var/spool/hylafax/etc/xferfaxlog

cups_log

This is the path to the CUPS page log file. Monitorix uses this file to report on print jobs.

Default value: /var/log/cups/page_log

ftp_log

This is the path to the FTP server (ProFTPD, vsftpd or Pure-FTPd) log. Monitorix uses this file to report FTP successful logins and other FTP-related information.

Default value: /var/log/proftpd/access.log

fail2ban_log

This is the path to the Fail2ban log file. Monitorix uses this file only if the option graph_mode has the value rate.

Default value: /var/log/fail2ban.log

spamassassin_log

This is the path to the Spamassassin log file. Monitorix uses this file to report spam-mail alerts.

Default value: /var/log/maillog

clamav_log

This is the path to the Clamav log file. Monitorix uses this file to report virus-mail alerts.

Default value: /var/log/clamav/clamav.log

cg_logdir

This is the path to the CommuniGate logs directory. Monitorix uses these files to report the number of mail messages successfully received and sent, and to report IMAP and POP3 successful logins.

Default value: /var/CommuniGate/SystemLogs/

squid_log

This is the path to the Squid log file. Monitorix uses this file to report on Squid Proxy requests.

Default value: /var/log/squid/access.log

imap_log_date_format

This is the Dovecot date format as it appears in the imap_log file.

Default value: %b %d

secure_log_date_format

This is secure_log date format.

Default value: %b %e

Piwik tracking code

enabled

This enables the inclusion of the Piwik tracking code in the main index.html file. Please refer to http://piwik.org/docs/tracking-api/ for more information on how to fill these fields.

Default value: n

Enable or disable graphs

graph_enable

This enables or disables the monitoring of each graph. Placing a y on a desired graph and restarting Monitorix will automatically create the RRD file for that graph and start gathering information according to its settings.

System load average and usage (system.pm)

This graph shows information about system load average (classical UNIX triplet), memory allocation, active processes (on Linux brought directly from the /proc directory), entropy and the system uptime.

loadavg_enabled

This section enables or disables the alert capabilities for this graph. Only the alert for the average CPU load is currently implemented. It works as follows:

This alert uses the minimum value between the second and the third load averages (those that represent the last 5 and 15 minutes), and if it reaches the loadavg_threshold value for the interval of time defined in loadavg_timeintvl, Monitorix will execute the external alert script defined in loadavg_script.

The idea to use min(load5, load15) is to obtain a more symmetric curve and a sooner cancellation of the alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

loadavg_timeintvl

This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed.

Default value: 3600

loadavg_threshold

This is the value that needs to be reached or exceeded within the specified time period in loadavg_timeintvl to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

The value of this option is compared against the last 15 minutes of CPU load average.

Default value: 5.0

loadavg_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in loadavg_timeintvl.
2nd - the value currently defined in loadavg_threshold.
3rd - the current 15min CPU load average.

Default value: /path/to/script.sh

time_unit

This is the unit in which will appear the values in the uptime graph. Possible values are: minute, hour or day. It will default to day even if none is specified.

Global kernel usage (kern.pm)

Note that the VFS graph is just informative of how the kernel is balancing its tables. graph_mode

This changes the layout of the kernel usage graph, the possible values are r for a real graph, or s for a stacked graph (every line or area is stacked on top of the previous element).

Default value: r

list

This is the list of values offered in modern Linux kernels. Older Linux kernels or other Operating Systems may not have all of them. Placing a y or an n will enable or disable the value in the graph.

Kernel usage per processor (proc.pm)

max

This is the number of processors or cores that your system has. There is no limit, however keep in mind that every time this number is changed Monitorix will resize the proc.rrd file accordingly, removing all historical data.

Default value: 4

graphs_per_row

This is the number of processor graphs that will be put in a row. Consider the interaction of this parameter with the size and data options (below) in order to adjust the size and number of graphs in relation to your horizontal screen size.

Default value: 2

size

This option sets the size of all processors graphs.

The possible values are:

large for 750x180 graphs.
main for 450x150 graphs.
medium for 325x150 graphs.
medium2 for 325x70 graphs.
small for 200x66 graphs.
mini for 183x66 graphs.
tiny for 110x40 graphs.

Default value: medium

DATA

This option will completely enable or disable the legend in the processor graphs.

Default value: y

AMD power consumption (amdenergy.pm)

This graph is able to monitor the power draw of an unlimited number of AMD CPUs if the amd_energy driver and sensors is available. I will show power draw of the cores and the socket and the non-core part of the power draw. It is calculated by subtracting the sum of the core power draw from the socket power draw.

list

This is a list of groups of CPU sensors you want to monitor with the same names as they appear in your sensors(1) command. Each group will become a plot and there may be an unlimited number of groups. You can define device names like amd_energy-isa-0000.

WARNING: Every time the number of groups or the size of the groups in this option changes, Monitorix will resize the amdenergy.rrd file accordingly, removing all historical data.

To collect the CPU power usage the energy counters from the sensors command via the amd_energy driver is used and a power consumption in the monitoring time interval calculated.

It is recommended that you first check if the sensors output is able to provide energy counters (EcoreXXX and EsocketX) from the CPU(s) that you plan to monitor. For example check sensors for available sensors. You may test this with the following command (root privileges might be needed to access the energy counters):

# sensors amd_energy-isa-0000
amd_energy-isa-0000
Adapter: ISA adapter
Ecore000: 31.81 kJ
Ecore001: 27.54 kJ
Ecore002: 25.44 kJ
Ecore003: 27.08 kJ
Ecore004: 48.45 kJ
Ecore005: 41.39 kJ
Ecore006: 42.49 kJ
Ecore007: 39.88 kJ
Ecore008: 109.67 kJ
Ecore009: 107.59 kJ
Ecore010: 115.21 kJ
Ecore011: 168.80 kJ
Ecore012: 61.64 kJ
Ecore013: 49.86 kJ
Ecore014: 42.20 kJ
Ecore015: 51.55 kJ
Ecore016: 35.41 kJ
Ecore017: 35.87 kJ
Ecore018: 33.91 kJ
Ecore019: 34.40 kJ
Ecore020: 102.11 kJ
Ecore021: 238.25 kJ
Ecore022: 86.68 kJ
Ecore023: 99.13 kJ
Ecore024: 23.79 kJ
Ecore025: 23.30 kJ
Ecore026: 23.48 kJ
Ecore027: 23.63 kJ
Ecore028: 23.53 kJ
Ecore029: 22.10 kJ
Ecore030: 20.83 kJ
Ecore031: 19.45 kJ
Esocket0: 21.12 MJ

If you see good results as above, you can add it to the group 0 like this:

<list>
0 = amd_energy-isa-0000
1 = amd_energy-isa-0001
</list>

number_of_cores

This list sets the number of cores for the CPUs specified in the list option. It is required to specify the number of cores is for each CPU in list

<number_of_cores>
amd_energy-isa-0000 = 64
amd_energy-isa-0001 = 32
</number_of_cores>

map

This list complements the list option. It basically allows you to change the CPU name that will appear in the graph, hiding the sensor name. If no association is defined, then Monitorix will display the name of the CPU device as it is specified in the config file.

<map>
amd_energy-isa-0000 = AMD CPU 1
amd_energy-isa-0001 = AMD CPU 2
</map>

desc

This list complements the list option. It allows you to include a title for every group of CPUs. The title will appear in the title above the plot.

<desc>
0 = Socket 1 power distribution
1 = Socket 2 power distribution
</desc>

socketpower_enabled

This section enables or disables the alert capabilities for this graph; the alert for the socket power draw. It works as follows:

If the socket power draw of any of the specified CPU device reaches or succeeds the socketpower_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in socketpower_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

socketpower_timeintvl

Not used in this alert.

Default value: None

socketpower_threshold

This is the value that needs to be reached or succeeded to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

Default value: None

socketpower_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in socketpower_timeintvl.
2nd - the value currently defined in socketpower_threshold.
3rd - the current socket power draw.

Default value: /path/to/script.sh

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

This option, when enabled via y, combined with the show_gaps option shows gaps only if all data points are nan instead of requiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation.

Default value: n

Intel RAPL power consumption (intelrapl.pm)

This graph is able to monitor the power draw of an unlimited number of Intel RAPL supporting devices like Intel CPU packages. For example it can (if the device RAPL data is available) show power draw of the cores, integrated GPU, package, DRAM and the non-core part of the power draw. The non-core power draw composition can be specified by setting which parts will be subtracted from the package power draw.

list

This is a list of groups of CPU sensors you want to monitor with an arbitrary name. Each group will become a plot and there may be an unlimited number of groups. You can define sensor names like ore and ackage.

WARNING: Every time the number of groups or the size of the groups in this option changes, Monitorix will resize the intelrapl.rrd file accordingly, removing all historical data.

To collect the CPU power usage the energy counters from the intel-rapl framework are used and a power consumption in the monitored time interval calculated.

It is recommended that you first check if the intel-rapl class tree and collect your desired energy counters from the devices that you plan to monitor. For example check tree /sys/class/powercap/intel-rapl for available energy_uj energy counters. The corresponding name files helps identifying the sensors.

You can add it to the group 0 like this:

<list>
0 = core, uncore, package, dram
1 = dram
</list>

list_item_names

This list complements the list option. It allows you to change the group name that will appear in the graph, hiding the sensor name. If no association is defined, then Monitorix will display the name of the device as it is specified in the config file.

<list_item_names>
0 = CPU 1
1 = DRAM modules
</list_item_names>

sensors

This list sets the energy counter files for the devices specified in the list option.

<sensors>
core = /sys/class/powercap/intel-rapl:0:0/energy_uj
uncore = /sys/class/powercap/intel-rapl:0:1/energy_uj
package = /sys/class/powercap/intel-rapl:0/energy_uj
dram = /sys/class/powercap/intel-rapl:0:2/energy_uj
</sensors>

sensor_names

This list complements the sensors option. It allows you to change the device name that will appear in the graph, hiding the device name. If no association is defined, then Monitorix will display the name of the device as it is specified in the config file.

<sensor_names>
package = Package
core = Cores
uncore = IGP
dram = DRAM
</sensor_names>

package_sensors

This list allows you to set a device name for the package device. This specified device is used as total power draw to calculate the non-core power draw by subtracting the power draw of the devices specified for the same group in ackage_sensors. Non-core power draw will not be shown if no package sensor is specified for a certain group.

<package_sensors>
0 = package
</package_sensors>

package_content

This list complements the package_sensors option. It allows specify the devices that are contained in the total package power draw. This information is needed if you want to visualize non-core power draw. Non-core power draw will be calculated by subtracting the sum power draw of a package content group from the package power draw.

<package_content>
0 = core, uncore
</package_content>

noncore_names

This list allows you to change the non-core name for a certain group that will appear in the graph legend.

<noncore_names>
0 = Non-Core
</noncore_names>

desc

This list complements the list option. It allows you to include a title for every group of devicess. The title will appear in the title above the plot.

<desc>
0 = CPU power distribution
1 = Memory power distribution
</desc>

sum

This list allows you to add a specific sum of devices to the plot of a certain group. No sum will be shown if not specified for the group.

<sum>
0 = package, dram
</sum>

sum_names

This list complements the seum option. It allows specify the name of the sum if desired.

<sum_names>
0 = Package + DRAM
</sum_names>

packagepower_enabled

This section enables or disables the alert capabilities for this graph; the alert for the package power draw. It works as follows:

If the package power draw specified by package_sensors of any of the specified device reaches or succeeds the packagepower_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in packagepower_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

packagepower_timeintvl

Not used in this alert.

Default value: None

packagepower_threshold

This is the value that needs to be reached or succeeded to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

Default value: None

packagepower_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in packagepower_timeintvl.
2nd - the value currently defined in packagepower_threshold.
3rd - the current package power draw.

Default value: /path/to/script.sh

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

show_noncore_info

This option, when enabled via y, enable showing description string in the legend how the non-core part is calculated.

Default value: n

max_number_of_values_per_group

This option sets the maximum number of devices per group if more values are required.

WARNING: Every time the max_number_of_values_per_group value changes, Monitorix will resize the intelrapl.rrd file accordingly, removing all historical data.

Default value: 10

HP ProLiant System Health (hptemp.pm)

This list will hold the defined temperature sensors for each graph. You must have installed the command hplog that comes with HP ProLiant System Health Application and Command Line Utilities.

Each graph has a limited number of IDs:

graph_0 up to 8 IDs.
graph_1 up to 6 IDs.
graph_2 up to 6 IDs.

The following is a configuration example of selected IDs:

alerts

This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed.

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the temperature that needs to be reached or exceeded within the specified time in time interval to execute the external script.

The script is the full path name of the script that will be executed by this alert.

Each defined sensor has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the first temperature sensor:

<alerts>
2 = 3600, 40, /path/to/script.sh
</alerts>

Such alert means that if the value of the sensor number 2 reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the value of the sensor.

LM-Sensors and GPU temperatures (lmsens.pm)

list

In this list you may specify the sensors you want to monitor with the same names as they appear in your sensors(1) command.

For example, imagine a sensors(1) output like this:

# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +51.0°C (high = +78.0°C, crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +49.0°C (high = +78.0°C, crit = +100.0°C)

f71882fg-isa-0a00
Adapter: ISA adapter
3.3V: +3.30 V
Vcore: +1.21 V (max = +2.04 V)
Vdimm: +1.82 V
Vchip: +1.38 V
+5V: +5.00 V
12V: +14.37 V
5VSB: +4.33 V
3VSB: +3.30 V
Battery: +3.22 V
CPU: 2035 RPM
System: 1765 RPM ALARM
Power: 2110 RPM ALARM
Aux: 2080 RPM ALARM
M/B Temp: +36.00 C
CPU Temp: +29.00 C

Then you may want to configure that list as:

<list>
core0 = Core 0
core1 = Core 1
mb0 = M/B Temp
cpu0 = CPU Temp
fan0 = CPU
fan1 = System
fan2 = Power
fan3 = Aux
volt0 = 3.3V
volt1 = VCore
volt2 = Vdimm
volt3 = Vchip
volt4 = \+5V
volt5 = 12V
volt6 = 5VSB
volt7 = 3VSB
volt8 = Battery
gpu0 = nvidia
</list>

Note that you need to escape the plus and minus signs in the voltage labels. It also recommended to enclose the values using double quotes.

The Fan values can be prefixed with the words rpm: (optional) or percent:. This will tell to Monitorix how to treat these values in the graph and in the case of the later it will add the percentage symbol (%) right after the value. Just like this:

<list>
fan0 = percent:Power
</LIST>

The last one, gpu0, is set here just in case you have a supported graphics card and want to monitor its temperature. Currently only NVIDIA and ATI graphic cards are supported; with the values nvidia and ati respectively, and it requires the official NVIDIA or ATI drivers.

If the temperature of your graphical card appears in the output of lm_sensors, then you can tell Monitorix to use it instead of using the official NVIDIA or ATI drivers. In that case, you need to prefix with lmsensors: the name of the temperature value. Just like this:

<list>
gpu0 = lmsensors:edge
</list>

This list has the following maximums allowed:

Up to 16 core keys (from core0 to core15).
Up to 2 mb keys (mb0 and mb1).
Up to 4 cpu keys (from cpu0 to cpu3).
Up to 9 fan keys (from fan0 to fan8).
Up to 12 volt keys (from volt0 to volt11).
Up to 9 gpu keys (from gpu0 to gpu8).

IMPORTANT NOTE: Sometimes the output of lm_sensors shows the same exact names for different temperature values and so Monitorix is unable to differentiate them. If you are under this situation please check the issue #131 (https://github.com/mikaku/Monitorix/issues/131) to solve this situation.

desc

This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the sensor. If no association is defined, then Monitorix will display the name of the key (left side) in the desc option (in uppercase in some graphs).

<desc>
mb0 = M/B
fan0 = CPUFan
gpu0 = ATI
</desc>

Please note that in the default graph all names are limited to 5 characters in order to fit up to 9 different values. In the zoomed graphs the limit is 8 characters.

alerts

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the temperature or volts, or whatever that needs to be reached or exceeded within the specified time in time interval to execute the external script.

The script is the full path name of the script that will be executed by this alert.

Each defined sensor has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the first temperature sensor:

<alerts>
core0 = 3600, 40, /path/to/script.sh
</alerts>

Such alert means that if the value of the sensor core0 reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the value of the sensor.

cmd

This is the command that will be used to gather statistics. This option may also be used to add new sensors values not covered by LM-Sensors by referencing an external script which executes the command sensors and others.

Default value: sensors

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

Generic sensors statistics (gensens.pm)

This graph helps to monitor up to three (so far) different sensors: temperatures, CPU frequencies and battery status which, depending of your machine, they should appear in the /sys directory.

list

This is a list of an unlimited number of groups to define the sensors to monitor. Each group is numbered starting from 0, and each one can hold up to 9 different entries separated by comma which corresponds to the names of the sensors present in your computer that you want to monitor. This module is capable to identify the type of the group by searching the substrings temp, cpu, bat, pwr, fan, pct and byt, so it will put automatically the vertical label in the graph accordingly (Celsius or Fahrenheit, Hz, Charge, Watts, RPM, Percent (%) and bytes respectively). Of course, it cannot supports mixed sensors in a same group. For example, if you need to monitor more than 9 temperature sensors just create a new group in list.

An example would be:

title

In this option you must associate a title with the group number specified in list. This is the title that will appear as the name of the graph. Following the settings in the example above:

<title>
0 = Temperatures
1 = CPU frequency
2 = Battery status
</title>

desc

In this option you must associate the complete pathname of the file from where to get the value of each entry defined in the list option. Following the settings in the example above:

<desc>
temp0 = /sys/devices/virtual/thermal/thermal_zone0/temp
temp1 = /sys/devices/virtual/thermal/thermal_zone1/temp
cpu0 = /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
cpu1 = /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq
cpu2 = /sys/devices/system/cpu/cpu2/cpufreq/scaling_cur_freq
cpu3 = /sys/devices/system/cpu/cpu3/cpufreq/scaling_cur_freq
bat0 = /sys/class/power_supply/BAT0/capacity
</desc>

unit

With this option you can define the order of magnitude associated to a specific value. The value collected will be divided by the value defined here. For instance, the temperature sensors tend to give the value in 1000ths of degrees Celsius, something like 28300, which will need to be divided by 1000 to get the real temperature of 28.3. In the case of CPU frequencies the values come in Mhz which means that they need to be converted to Hz by dividing them by 0.001. Since the battery value represents a percentage, it doesn't need any special calculation. Therefore you can define something like this:

map

With this option you can optionally rename any of the sensor names defined in the list option. Following the above example:

<map>
temp0 = Temperature Zone 0
temp1 = Temperature Zone 1
cpu0 = CPU0 frequency
cpu1 = CPU1 frequency
cpu2 = CPU2 frequency
cpu3 = CPU3 frequency
bat0 = Battery 0
</map>

All names are limited to 20 characters.

alerts

This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has four fields separated by comma: the time interval, the threshold, the path to the script to be executed and when the alert must be triggered. the last field is optional.

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the value (temperature, Hz or battery charge) that needs to be reached or exceeded within the specified time in time interval to execute the external script. It can be specified as a unique value or as a range of two values separated by a dash.

The script is the full path name of the script that will be executed by this alert.

The when value specifies when the alert must be triggered (above or below) the threshold, being above the default value when it's not specified. This forth parameter is only relevant when the threshold value is not a range.

Each defined sensor has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the first temperature sensor:

<alerts>
temp0 = 3600, 40, /path/to/script.sh, above
temp1 = 3600, 10, /path/to/script.sh, below
temp2 = 3600, 40-60, /path/to/script.sh
</alerts>

The first alert means that if the value of the sensor temp0 exceeds above 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The second alert means that if the value of the sensor temp1 exceeds below 10 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The third alert means that if the value of the sensor temp2 exceeds either below 40 or above of 60 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the value of the sensor.
4th - the direction or when that alert was triggered by (above or below).

IPMI sensor statistics (ipmi.pm)

This graph is able to monitor an unlimited number of IPMI sensors (temperatures, fans and voltages).

list

This is a comma-separated list that describes the groups of sensors in desc. Put one description for each group. For every group specified you need to specify its sensors in the desc option.

WARNING: Every time the number of entries in this option changes, Monitorix will resize the ipmi.rrd file accordingly, removing all historical data.

An example would be:

list = Temperatures, Fans, Voltages

desc

This is a list of sensors per group defined.

<desc>
0 = CPU Temp, System Temp
1 = FAN 1
2 = Vcore, 3.3VCC, 12V, VDIMM, 5VCC, CPU VTT, VBAT, VSB, AVCC
</desc>

The maximum number of sensors allowed for each group is 9.

units

This is the type of sensor in each group. It's important to not mix different type of sensors in a same group. This value is informative only, it's mostly used as a title for the y-axis in the graphs and should match with the output of the ipmitool command.

map

This list complements the desc option. It basically allows you to change the name that will appear in the graph, hiding the real name of the sensor. If no association is defined, then Monitorix will display the name specified in the desc option. Note, this only works in names that don't include whitespaces unless you use the whitespace_key_support option and replace whitespaces with underscores in the key.

alerts

This optional list enables the alert capabilities for this graph and complements with the desc option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed.

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the temperature that needs to be reached or exceeded within the specified time in time interval to execute the external script.

The script is the full path name of the script that will be executed by this alert.

Each defined sensor has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the first temperature sensor:

<alerts>
CPU_Temp = 3600, 40, /path/to/script.sh
</alerts>

Notice that the spaces in the sensor's name must be converted to underscores, since a variable can hold spaces in its name.

Such alert means that if the value of the sensor CPU_Temp reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the value of the sensor.

whitespace_key_support

This list complements the map option. It changes the handling of the key names. Without this option enabled you can't rename keys with whitespaces using the map option. When enabled, whitespaces in the map key will be replaced by underscores(_) and enables you to specify the key names this way.

Default value: n

graphs_per_row

This is the number of graphs that will be put in a row.

Default value: 2

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

extra_args

This option includes any extra argument to the ipmitool command executed by Monitorix, which is "ipmitool <extra_args> sdr". This is specially useful if you need to monitor a remote server. An example would be:

extra_args = -H <remote_ip> -U root -P <password>

Default value: none

Ambient sensor statistics (ambsens.pm)

This graph is able to monitor an unlimited number of ambient sensors (temperatures, humidity, barometer, etc.).

list

This is a comma-separated list that describes the type of sensors in desc. Put one description for each type. For every type specified you need to specify its sensors in the desc option. Each one most be referenced as a numeric value starting from zero in the desc option. There you will define all the sensors than come with that type of sensor.

WARNING: Every time the number of entries in this option changes, Monitorix will resize the ambsens.rrd file accordingly, removing all historical data.

An example would be:

list = Ambient temperature, Humidity

desc

This is a list of sensors per type defined. The name is irrelevant.

The maximum number of sensors allowed for each type is 9.

units

This is the class of sensor for each type. It's important to not mix different type of sensors in a same group. This value is informative only, it's mostly used as a title for the y-axis in the graphs.

cmd

This list complements the desc option. It basically allows you to associate a script or program (which may include arguments) that will be executed to retrieve the value for each sensor.

map

alerts

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the value (temperature, etc.) that needs to be reached or exceeded within the specified time in time interval to execute the external script. It can be specified as a unique value or as a range of two values separated by a dash.

The script is the full path name of the script that will be executed by this alert.

Each defined sensor has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the first temperature sensor:

<alerts>
temp0 = 3600, 40, /path/to/script.sh, above
temp1 = 3600, 10, /path/to/script.sh, below
temp2 = 3600, 40-60, /path/to/script.sh
</alerts>

The first alert means that if the value of the sensor temp0 exceeds above 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The second alert means that if the value of the sensor temp1 exceeds below 10 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The third alert means that if the value of the sensor temp2 either exceeds below 40 or above of 60 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the value of the sensor.
4th - the direction or when that alert was triggered by (above or below).

graphs_per_row

This is the number of graphs that will be put in a row.

Default value: 2

scientific_notation

This is an option to enable scientific notation for the current value in the legend.

Default value: n

show_average

This is an option to show also average, minimum and maximum values in the legend

Default value: n

AMD GPU temperatures and usage (amdgpu.pm)

This graph is able to monitor an unlimited number of AMD GPUs as long as the driver provides a hwmon interface. Usually it is not guaranteed to always get the same hwmon path so it is advised to assign fixed links via udev rules.

list

This is a list of groups of GPUs that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. You can define device names like amd-w6800.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the amdgpu.rrd file accordingly, removing all historical data.

To collect the GPU temperatures and usage data the hwmon subsystem is used.

It is recommended that you first check if the hwmon subsystem is able to provide data from the GPU(s) that you plan to monitor. For example check /sys/class/hwmon/hwmon1 for available sensors.

You can add it to the group 0 like this:

The maximum number of GPUs allowed per group is 8.

sensors

This list specifies the sensor locations in absolute paths. If a certain card does not have a specific sensor you leave the entry empty instead (/path/sensor_file1, , /path/sensor_file2). The order has to be: GPU busy percent, memory busy percent, GPU clock, memory clock, memory used, power consumption, power limit, fan pwm value, GPU temperature, junction temperature, memory temperature. Power consumption and limit will be shown in one plot.

<sensors>
amd-rx6900 = /dev/amd-rx6900/device/gpu_busy_percent, /dev/amd-rx6900/device/mem_busy_percent, /dev/amd-rx6900/freq1_input, /dev/amd-rx6900/freq2_input, /dev/amd-rx6900/device/mem_info_vram_used, /dev/amd-rx6900/power1_average, /dev/amd-rx6900/power1_cap, /dev/amd-rx6900/pwm1, /dev/amd-rx6900/temp1_input, /dev/amd-rx6900/temp2_input, /dev/amd-rx6900/temp3_input

</sensors>

map

This list complements the list option. It basically allows you to change the GPU name that will appear in the graph, hiding the real device name. If no association is defined, then Monitorix will display the name of the GPU device as it is.

desc

This list complements the list option. It basically allows you to include a title for every group of GPUs. The title will appear in the title of the graph.

<desc>
0 = Host
1 = Virtual

coretemp_enabled

This section enables or disables one of the alert capabilities for this graph; the alert for the core temperature. It works as follows:

If the core temperature of any of the specified GPU device names reaches or subceeds the coretemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in coretemp_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

coretemp_timeintvl

Not used in this alert.

Default value: 0

coretemp_threshold

This is the value that needs to be reached or subceeded to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

Default value: 10

coretemp_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in coretemp_timeintvl.
2nd - the value currently defined in coretemp_threshold.
3rd - the current core temperature.

Default value: /path/to/script.sh

memorytemp_enabled

This section enables or disables one of the alert capabilities for this graph; the alert for the memory temperature. It works as follows:

If the memory temperature of any of the specified GPU names reaches or exceeds the memorytemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in memorytemp_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

memorytemp_timeintvl

Not used in this alert.

Default value: 0

memorytemp_threshold

This is the value that needs to be reached or exceeded to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

Default value: 90

memorytemp_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in memorytemp_timeintvl.
2nd - the value currently defined in memorytemp_threshold.
3rd - the current memory temperature.

Default value: /path/to/script.sh

accept_invalid_amdgpu

During the init stage this graph verifies that every defined device name does exist in the system. If not, then the graph disables itself.

This option changes this behaviour and permits one to continue working even if the device names defined doesn't exist. Keep in mind that you will continue seeing error messages in the logfile.

Default value: n

show_current_values

Print current values in the legend of the small righthand plots.

Default value: n

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

respect_power_state

This option, when enabled via y, will respect the AMD GPU D3 power state. Monitorix won't wake up a GPU in D3 power state to check the sensors values but skip it. The power state sensor has to be specified via the ower_states option for each GPU that should be respected.

Default value: n

power_states

This list complements the respect_power_state option. You can specify the power_state sensor for each GPU that should not be woken up if in D3.

<power_states>
amd-w6800 = /dev/hwmon-w6800/device/power_state
amd-rx6900 = /dev/hwmon-rx6900/device/power_state
</power_states>

NVIDIA GPU temperatures and usage (nvidiagpu.pm)

This graph is able to monitor an unlimited number of Nvidia GPUs via nvidia-smi.

list

This is a list of groups of GPUs that you want to monitor. Each group will become a graph and there may be an unlimited number of groups.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the nvidiagpu.rrd file accordingly, removing all historical data.

As identifier you can either use the GPU ID or the GPU UUID found via nvidia-smi --list-gpus. You can add it to the group 0 like this:

The maximum number of GPUs allowed per group is 8.

Disk drive temperatures and health (disk.pm)

This graph is able to monitor an unlimited number of disk drives.

list

This is a list of groups of disk drives that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. You can define device names or paths to devices like /dev/disk/by-path/pci-0000:00:11.0-scsi-0:0:0:0.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the disk.rrd file accordingly, removing all historical data.

To collect the disk drive temperatures and health the smartmontools or the hddtemp command are required. Depending on the disk model reading smart values will wake up the disk and reset the sleep timer. To avoid waking them up set respect_standby = y but they still won't got to sleep automatically.

It is recommended that you first check if either smartctl(8) or hddtemp are able to collect data from the disk drive(s) that you plan to monitor. You may test this with the following command:

# hddtemp /dev/sda
/dev/sda: WDC WD1600AABS-00M1A0: 48°C

If you see good results as above, you can add it to the group 0 like this:

The maximum number of disk device names allowed per group is 8.

map

This list complements the list option. It basically allows you to change the disk name that will appear in the graph, hiding the real device name. If no association is defined, then Monitorix will display the name of the disk as it is.

NVME drive temperatures and health (nvme.pm)

This graph is able to monitor an unlimited number of nvme drives.

list

This is a list of groups of nvme drives that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. You can define device names or paths to devices like /dev/nvme0.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the nvme.rrd file accordingly, removing all historical data.

To collect the nvme drive temperatures and health the smartmontools command are required.

It is recommended that you first check if smartctl(8) is able to collect data from the nvme drive(s) that you plan to monitor. You may test this with the following command:

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in percentused_timeintvl.
2nd - the value currently defined in percentused_threshold.
3rd - the current number of life percentage used.

Default value: /path/to/script.sh

accept_invalid_nvme

During the init stage this graph verifies that every defined device name does exist in the system. If not, then the graph disables itself.

This option changes this behavior and permits one to continue working even if the device names defined doesn't exist. Keep in mind that you will continue seeing error messages in the logfile.

Default value: n

show_extended_plots

Default value: n

gap_on_all_nan

Default value: n

Filesystem usage and I/O activity (fs.pm)

This graph is able to monitor an unlimited number of filesystems.

list

This is a list of groups of mounted filesystems that you want to monitor. Each group will become a graph and there may be an unlimited number of groups.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the fs.rrd file accordingly, removing all historical data.

Take special care to use the same name as appears in the output of the df(1) command (the swap device is a special case). An example would be:

<list>
0 = /, swap, boot, home, /mnt/backup
</list>

The maximum number of filesystems allowed per group is 8.

desc

This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the mount point. If no association is defined, then Monitorix will display the name specified in the list option.

<desc>
/ = Root FS
/home = My Home
/mnt/backup = Backups
</desc>

You can define as much entries as you want.

devmap

This optional list complements the list option. When Monitorix is started, and in order to be able to show I/O activity, it attempts to detect the mapping of devices specified in list, as defined in the df command output column "Mounted on". In the event that devices are not detected by Monitorix, the devmap option shall be used to manually define them, according to the underlying OS:

Linux (kernel > 2.4)

<devmap> device must match a device listed in the "/proc/diskstats" file.

Linux (kernel <= 2.4)

<devmap> is not used, but because something is defined in <devmap>, Monitorix will extract "disk_io" lines from the "/proc/stat" file.

FreeBSD

<devmap> device recognized by the output of "iostat -xI <dev>" command.

OpenBSD and NetBSD

<devmap> is not used, but because something is defined in <devmap>, Monitorix will use the output of "iostat -DI" command.

Just an example:

<devmap>
/mnt/home = dm-1
/mnt/backup = cciss/c0d2p6
</devmap>

You can define as much entries as you want.

alerts

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the percentage of disk space used in the file system that needs to be reached or exceeded within the specified time in time interval to execute the external script.

The script is the full path name of the script that will be executed by this alert.

Each defined filesystem has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the root filesystem:

<alerts>
/ = 3600, 98, /path/to/script.sh
</alerts>

Such alert means that if the percentage of disk space used in the root filesystem reaches or exceeds 98 (more than 98) during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the filesystem disk usage.

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

has_removable_devices

This option, when enabled via y, solves the problem with those hotpluggable devices that were offline when Monitorix was started, and later when they went online Monitorix don't know their device names and do not appear in the I/O statistics graphs, unless you restart Monitorix. So, when this option is enabled Monitorix will re-check the devices on every update.

Default value: n

ZFS statistics (zfs.pm)

This graph is able to monitor an unlimited number of pools.

max_pools

This is the maximum number of pools that you can define in list. There is no limit to the number of pools monitored, but keep in mind that every time this number changes, Monitorix will resize the zfs.rrd file accordingly, removing all historical data.

Default value: 5

list

This is a comma-separated list of pool names. The number of pool names defined here can't be greater than the number defined in max_pools.

Directory usage statistics (du.pm)

This graph is able to monitor the usage of an unlimited number of directories.

IMPORTANT NOTE: The du command makes intensive disk I/O access that might slow down the whole system. Moreover, continued executions of this command will affect the buffer cache mechanism and this will also increase the system response time. To reduce executions refresh_interval can be specified in seconds (Use 0 for default refresh interval).

list

This is a comma-separated list that describes the groups of directories in desc. Put one description for each group. For every group specified you need to specify its directories in the desc option.

WARNING: Every time the number of entries in this option changes, Monitorix will resize the du.rrd file accordingly, removing all historical data.

An example would be:

list = System, Users

desc

This is a list of directories per group defined.

<desc>
0 = /var/spool/mail, /var/spool/mqueue, /etc, /var/ftp, /tmp
1 = /home/ace, /home/gene, /home/paul, /home/peter
</desc>

The maximum number of directories allowed for each group is 9.

type

This specifies the information that will be presented for each directory specified in each list. It accepts two possible values:

size for the directory size (which is the default option).
files for the number of files inside the directory.

An example would be:

<type>
0 = size
1 = files
</type>

dirmap

This list complements the desc option. It basically allows you to change the name that will appear in the graph, hiding the real name of the directory. If no association is defined, then Monitorix will display the name specified in the desc option.

graphs_per_row

This is the number of graphs that will be put in a row.

Default value: 2

extra_args

This option includes any extra argument to the du command executed by Monitorix, which is "du -ks". This is specially useful if you want to skip directories on different file systems, in this case just define this option like this:

extra_args = "-x"

IMPORTANT NOTICE: Keep in mind that including certain flags like '-h' (which gives results in human readable format) could make Monitorix unable to interpret the results.

refresh_interval

Refresh interval in seconds. This is an option to reduce the execution of the du command and undesired side effects caused by this. Default value 0 means normal refresh with all other plots. Besides the default meaningful values are from 60 to 86400. Keep in mind that changing the refresh_interval is possible without loosing history but changing the interval to a smaller one will introduce gaps in the data at the transition point.

Default value: 0

use_nan_for_missing_data

This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data.

Default value: n

gap_on_all_nan

Default value: n

Network traffic and usage (net.pm)

max

This is the maximum number of network interfaces that you can define in list. There is no limit, but keep in mind that every time this number changes, Monitorix will resize the net.rrd file accordingly, removing all historical data.

Default value: 10

list

This is a comma-separated list of network interfaces that you may want to monitor. An example would be:

list = eth0, eth1

desc

This is the option where each network interface specified in list is described. Each definition consists of three parameters separated by comma: the description of the interface and the rigid and limit values.

Put one description for each interface listed. An example would be:

<desc>
eth0 = FastEthernet LAN, 0, 1000
eth1 = ADSL 10Mbs Internet, 0, 1000
</desc>

gateway

This is where the network interface that acts as the gateway for this server is defined. This is mainly used if you plan to monitor network traffic usage of your devices/networks using the traffacct graph below.

Netstat statistics (netstat.pm)

This graph shows the state of the all IPv4 and IPv6 network connections.

Only the command to be used can be set here, besides the limit and rigid values.

cmd

This is the command that will be used to gather statistics. There are two possible values:

ss
netstat

Default value: ss

Tinyproxy statistics (tinyproxy.pm)

This graph is able to monitor an unlimited number of Tinyproxy installations.

list

This is a comma-separated list of URLs of Tinyproxys.

WARNING: Every time the number of entries in this option changes, Monitorix will resize the tinyproxy.rrd file accordingly, removing all historical data.

Default value: http://your.proxy.com/

desc

This list complements the list option, it defines the URL from where Monitorix must gather the statistics for each Tinyproxy defined.

An example of this option would be:

<desc>
http://your.proxy.com = http://tinyproxy.stats
</desc>

show_url

If set to y Monitorix will show the original URL of each Tinyproxy at the bottom of the graph. For security reasons you may want to hide this information.

Default value: y

Traffic Control statistics (tc.pm)

This graph is able to monitor an unlimited number of network interfaces managed by the tc command.

list

This is a comma-separated list of network interfaces that you may want to monitor. An example would be:

list = eth0, eth1

desc

This is the option where you define the queue disciplines you want to monitor for each network interface specified in list.

An example would be:

<desc>
eth0 = cbq 1, sfq 10, sfq 20, sfq 30, ingress ffff
eth1 = htb 1, pfifo 20, pfifo 21, pfifo 22
</desc>

The maximum number of qdiscs allowed is 9.

map

This option complements the desc option. It basically allows you to change the name of the qdiscs that will appear in the graphs. If no association is defined, then Monitorix will show the name as specified in the desc option.

Since the qdisc names have the space character in their names, they can't be used as the key in the association, instead you must the use their position number (starting by 0) in the desc option.

An example would be:

<map>
<eth0>
0 = Class Based Queueing
1 = Stochastic Fairness Queueing 10
</eth0>
<eth1>
0 = Hierarchical Token Bucket
</eth1>
</map>

Libvirt statistics (libvirt.pm)

This graph is able to monitor an unlimited number of virtual machines managed by Libvirt.

cmd

This is the command that will be used to gather statistics from each virtual machine listed in list.

Default value: virsh

An example would be:

cmd = virsh -r -c qemu:///session

list

This is a list of groups of virtual machines that you want to monitor. Each group will become a graph and there may be an unlimited number of groups.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the libvirt.rrd file accordingly, removing all historical data.

An example would be:

<list>
0 = centos6, winxp
</list>

The maximum number of virtual machines allowed per group is 8.

desc

This list complements the list option and is mandatory for every virtual machine listed. You must define the virtual block device and the MAC address of the virtual network device that you want to monitor for every virtual machine. Just like this:

<desc>
centos6 = CentOS 6, vda, 52:54:00:45:d0:e7
winxp = MS Windows XP, hda, 52:54:00:97:1c:e5
</desc>

You might also define this list using sections for each virtual machine, this way you'll be able to define multiple disks and multiple network interfaces for each virtual machine. Just like this:

<desc>
<centos6>
desc = "CentOS 6"
disk = vda, vdb, vdc
net = 52:54:00:45:d0:e7, 52:54:00:45:d0:e8
</centos6>
</desc>

To obtain all these values you might want to use the following commands:

# virsh domblklist centos6
Target Source
------------------------------------------------
vda /home/jordi/kvm/centos6.img
hdc -

# virsh domiflist centos6
Interface Type Source Model MAC
-------------------------------------------------------
vnet3 network default virtio 52:54:00:45:d0:e7

This option also allows you to change the name that will appear in the graph, hiding the real name of the virtual machine. If no association is defined, then Monitorix will display the name specified in the list option.

Process statistics (process.pm)

This graph is able to monitor an unlimited number of processes. This graph requires a Linux kernel version 2.6.20 at least to support process I/O accounting. Some systems with older kernels might also have been ported it though.

list

This is a list of groups of processes that you want to monitor. Each group will become a graph and there may be an unlimited number of groups.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the process.rrd file accordingly, removing all historical data.

Monitorix uses the following command to find the processes listed in this option:

# ps -eo pid,comm,command

Therefore names in the process list can be either exactly to the process name as it appears in the comm columns, or just a substring of the process name that appears in the command column.

An example of this option would be:

<list>
0 = httpd, sshd, ntpd, mysqld, proftpd, clamd, imap, sendmail, named, bash
</list>

The maximum number of processes allowed per group is 10.

desc

This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the process. If no association is defined, then Monitorix will display the name specified in the list option.

<desc>
httpd = Apache
imap = Dovecot
named = Bind
</desc>

You can define as much entries as you want.

time_unit

This is the unit in which will appear the values in the uptime graph. Possible values are: minute, hour or day. It will default to day even if none is specified.

System services demand (serv.pm)

This graph is able to monitor an unlimited number of system services or any application that has a log file.

list

This is a list of groups of services that you plan to monitor. Each group will become a graph and there may be an unlimited number of groups.

WARNING: Every time the number of groups in this option changes, Monitorix will resize the serv.rrd file accordingly, removing all historical data.

An example of this option would be:

<list>
Default = SSH, FTP, TELNET, IMAP, Samba, Fax, CUPS, POP3, SMTP, Spam, Virus, Fail2ban
</list>

The maximum number of services allowed per group is 16.

desc

This list complements the list option. It basically allows you to define how Monitorix will monitor such service.

You must use the same name of service that you defined in list followed by an equal sign and a number of values. The first value indicates if this will be a C (counter) or a G (gauge). Counters are perfect for values that accumulate on every sample (match lines in logfiles), Gauges are for values that can change on every new sample (disk usage, Samba users, etc). The second value indicates the logfile from where Monitorix will extract the information. It must be prefixed with file: to indicate that it's a file. If you need to use the output of a program instead, then you can prefix it with exec: and Monitorix will run this script and will use its output as if it was the logfile.

The third value is the first regular expression that Monitorix will use to match lines. It's normally used as the date that appears in the log file.

The forth and last value is a group of regular expressions separated by a plus sign. You can prefix a regular expression with i: in order to note that it must be insensitive case.

You can create multiple definitions of the same service with different values, so you are able to combine similar services into one single metric.

<desc>
SSH = C, file:/var/log/secure, "^%b %e", "sshd\[.*\]: Accepted "
Spam = C, file:/var/log/maillog, "^%b %e", "MailScanner.*Spam Checks:.*Found.*spam messages" + "amavis\[.* SPAM"
Spam = C, file:/var/log/sa-update.log, "^%b %e", "spamd: identified spam"
SMTP = C, file:/var/log/maillog, "^%b %e", i:"to=.*stat(us)?=sent"
IMAP = C, file:/var/log/uwimap, "%b %d", " imapd\[.* Login user="
IMAP = C, file:/var/log/dovecot, "%b %d", " imap-login: .* Login: "
Samba = G, exec:/usr/local/bin/samba.sh, "", ""
POP3 = C, file:/var/log/uwimap, "%b %d", " ipop3d\[.* Login user="
POP3 = C, file:/var/log/dovecot, "%b %d", " pop3-login: .* Login: "
</desc>

You can define as much entries as you want.

mode

This option toggles the way the System Services Demand data is represented in the graph. There are two possible values:

i for incremental style.
l for load (peaks) style.

Default value: i

graphs_per_row

This is the number of graphs that will be put in a row.

Default value: 2

Mail statistics (mail.pm)

This graph requires either MailScanner or amavisd-new mail scanners in order to account spam and virus emails. Spamassassin and Clamav antivirus are also used for spam and virus email accounting.

mta

This option specifies the MTA that Monitorix will use to collect mail statistics. The currently supported MTAs are:

Sendmail
Postfix
Exim

NOTE: the pflogsumm utility is required when using the Postfix MTA.

Default value: sendmail

greylist

This option specifies the Greylisting implementation that Monitorix will use to collect statistical information.

The currently supported Greylisting software is:

milter-greylist
postgrey

In the case of milter-greylist, Monitorix shows the same data that appears at the end of the file greylist.db.

In the case of Postgrey, Monitorix reads the mail_log file and searches for a specific type of lines. Lines of type "action=greylist, reason=new" appear as Greylisted in the graph. Lines of type "action=greylist, reason=early-retry" appear as Delayed in the graph. Lines of type "action=pass, reason=triplet found" appear as Passed in the graph. And finally, lines of type "action=pass, reason=client whitelist" appear as Whitelisted in the graph.

Default value: milter-greylist

stats_rate

This option only affects the Mail Statistics and the Greylisting graphs, and it specifies the rate in which the values are saved and shown. This option has two possible values:

real
per_second

If it's set to its default value (real), it will show the messages as in a 'per minute' rate. Since Monitorix collects data on every minute, this should be the preferred way to see the results.

In the other hand, and in order to keep backwards compatibility, if this option is missing in the configuration file, it will act as if it was set up as per_second, which means that the number of messages collected in each minute will be divided by 60.

Default value: real

delvd_enabled

This section enables or disables one of the alert capabilities for this graph; the alert for the number of delivered messages. It works as follows:

If the number of delivered messages reaches the delvd_threshold value for the interval of time defined in delvd_timeintvl, Monitorix will execute the external alert script defined in delvd_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

delvd_timeintvl

This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed.

Default value: 60

delvd_threshold

This is the value that needs to be reached or exceeded within the specified time period in delvd_timeintvl to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

The value of this option is compared against the number of delivered messages since the last delvd_timeintvl seconds.

Default value: 100

delvd_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in delvd_timeintvl.
2nd - the value currently defined in delvd_threshold.
3rd - the number of delivered messages.

Default value: /path/to/script.sh

mqueued_enabled

This section enables or disables one of the alert capabilities for this graph; the alert for the number of queued messages. It works as follows:

If the number of queued messages reaches the mqueued_threshold value for the interval of time defined in mqueued_timeintvl, Monitorix will execute the external alert script defined in mqueued_script.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

Default value: n

mqueued_timeintvl

This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed.

Default value: 3600

mqueued_threshold

This is the value that needs to be reached or exceeded within the specified time period in mqueued_timeintvl to trigger the mechanism for a particular action, which in this case is the execution of an external alert script.

The value of this option is compared with the number of messages in the mail queue.

Default value: 100

mqueued_script

This is the full path name of the script that will be executed by this alert.

It will receive the following three parameters:

1st - the value currently defined in mqueued_timeintvl.
2nd - the value currently defined in mqueued_threshold.
3rd - the number of messages in the mail queue.

Default value: /path/to/script.sh

Network port traffic (port.pm)

This graph requires the iptables(8) command and optionally the ip6tables(8) command on Linux systems and the ipfw command on *BSD systems.

max

This is the number of network ports that you want to monitor. There is no limit to the number of ports monitored, but keep in mind that every time this number changes, Monitorix will resize the port.rrd file accordingly, removing all historical data.

Default value: 9

rule

This is the rule number that Monitorix will use when using the ipfw command to manage network port activity on *BSD systems. Change it if you think it might conflict with any other rule number.

Default value: 24000

list

You may define here up to max network port numbers. If you need to monitor the same network port with TCP and UDP protocols, you can add your own suffix to the port number (e.g: 443t and 443u) in order to distinguish it from the double definition in the <desc> block. It also support port ranges (e.g: 49152:65534) to be able to monitor the traffic of a number of consecutive ports summarized on a unique graph.

If you see a red color in the background of a network port graph, it means that there is not a daemon listening on that port. This can be useful to know if some service gone down unexpectedly. Of course, this is only valid on a single port, not ranged ports.

desc

This is the option where each network port specified in list is described. Each port definition consists of six parameters separated by comma:

- an small port description.
- the network protocol (tcp or udp).
- the connection type (in, out or in/out).
- the rigid value.
- the limit value.
- the L optional option which specifies that this port should be listening and Monitorix will advice it, by changing the background color of the graph to red, if finds it down. This option has no effect on ranged ports.

There is also support (Linux only) for IPv6 network ports activity by using protocol names as tcp6 or udp6.

An example would be:

list = 25, 25ip6, 80, 53t, 53u, 49152:65534
<desc>
25 = SMTP, tcp, in/out, 0, 1000, L
25ip6 = SMTP, tcp6, in/out, 0, 1000, L
80 = HTTP, tcp, in, 0, 1000, L
53t = DNS, tcp, in, 0, 1000, L
53u = DNS, udp, in, 0, 1000, L
49152:65534 = FTP_PSV, tcp, in, 0, 1000
</desc>

As you can see, you cannot use the same port number twice. Instead, you must distinguish it with some suffix. Monitorix will automatically extract all the first numeric digits, and will use that value as the network port number.

graphs_per_row

This is the number of graphs that will be put in a row. Consider the interaction of this parameter with the max option in order to adjust the size and number of graphs in relation to your horizontal screen size.

Default value: 3

size

This is the size of the graphs of the ports. It currently accepts up to 8 different size names: large, main, medium, medium2, small, mini, tiny, zoom and remote. You can check the resolution of each size in the configuration file, inside the list named graph_size.

Default value: mini

cmd

This option is used only under Linux systems. It is intended to define the command (with or without its complete path) that will be used to test if the network port is down (not listening). Currently there are only two possible values:

ss
netstat

Default value: ss

Users using the system (user.pm)

Only the limit and rigid values can be set here.

FTP statistics (ftp.pm)

This graph supports currently ProFTPD, vsftpd and Pure-FTPd log file formats.

For best results with the ProFTPD server I recommend to add the following line in its configuration file:

ExtendedLog /var/log/proftpd/access.log AUTH,DIRS,READ,WRITE

For best results with the vsftpd server I recommend to setup the option xferlog_std_format to NO, and the option ftp_log to /var/log/vsftpd.log.

Pure-FTPd users might want to consider using the system syslog logfile.

server

This option specifies the FTP server. The currently supported FTP servers are:

ProFTPD
vsftpd
Pure-FTPd

Default value: proftpd

anon_user

This option lists the different names (separated by comma) that can adopt the Anonymous user in the FTP server defined in server.

Default value: anonymous, ftp

Apache statistics (apache.pm)

This graph requires that mod_status be loaded and ExtendedStatus option set to On in order to collect full status information of the Apache web server.

This graph is able to monitor an unlimited number of local and remote Apache web servers.

list

This is a comma-separated list of URLs of the monitored Apache web servers.

WARNING: Every time the number of entries in this option changes, Monitorix will resize the apache.rrd file accordingly, removing all historical data.

Default value: http://localhost/server-status?auto

alerts

The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is executed.

The threshold is the number of remaining free slots that needs to be reached or exceeded within the specified time in time interval to execute the external script.

The script is the full path name of the script that will be executed by this alert.

Each defined Apache has its own alert.

The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

The following is an example of an alert defined for the local Apache:

<alerts>
http://localhost/server-status?auto = 3600, 5, /path/to/script.sh
</alerts>

Such alert means that if the remaining free slots reaches or exceeds 5 (less than 5) during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed.

The external script will receive the following arguments:

1st - the value defined as time interval.
2nd - the value defined as threshold.
3rd - the remaining free slots.

Nginx statistics (nginx.pm)

This graph may require adding some lines in the configuration file nginx.conf. Please see the README.nginx file to determine the exact steps needed to configure Nginx to get status information.

This graph requires the iptables(8) command on Linux systems, and the ipfw command on *BSD systems.

url

This is the URL to be used to collect Nginx stats.

Default value: http://localhost/nginx_status

port

This is the network port the Nginx web server is listening on. It will be used for traffic (with iptables), and for nginx_status if url is not specified. If port of nginx_status is different from port then specify it in the url (http://host:port/nginx_status)

Default value: 80

rule

This is the rule number that Monitorix will use when using the ipfw command to manage Nginx network activity on *BSD systems. Change it if you think it might conflict with any other rule number.

Default value: 24100

cmd

This is the command that will be used to test if the Nginx web server is down (not listening). There are two possible values:

ss
netstat

Default value: ss

Lighttpd statistics (lighttpd.pm)

This graph requires that mod_status is loaded in order to collect status information from the Lighttpd web server.

This graph is able to monitor an unlimited number of local and remote Lighttpd web servers.

list

This is a comma-separated list of URLs of the monitored Lighttpd web servers.

WARNING: Every time the number of entries of this option changes, Monitorix will resize the lighttpd.rrd file accordingly, removing all historical data.

Default value: http://localhost/server-status?auto

MySQL statistics (mysql.pm)

This graph requires that you create a password protected MySQL user that is NOT granted privileges on any DB.

Example:

mysql> CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
mysql> FLUSH PRIVILEGES;

where user is the new user name and password is the password that will be used for that user.

This graph is able to monitor an unlimited number of local and remote MySQL web servers.

NOTE: It is strongly recommended that you restart the MySQL service in order to avoid high peaks that could prevent correct display of the first plotted data.

conn_type

This option toggles the way how Monitorix establishes the connection with the MySQL server. There are two possible values:

host using the network (hostname and IP address).
socket using a socket file.

Default value: host

list

This is a comma-separated list of hostnames or path to sockets of MySQL servers.

WARNING: Every time the number of entries of this option change Monitorix will resize the mysql.rrd file accordingly, removing all historical data.

Default value: localhost

desc

This is the option where each entry specified in the list is described. Each definition consists of three parameters separated by comma: the port, the username and the password.

An example using the host type would be:

<desc>
localhost = 3306, user, secret
</desc>

When using the socket type the network port is, of course, irrelevant but its field is still mandatory. This means that you must respect the three comma-separated values.

Some of the values shown in the graphs are the result of a calculation of two values from either SHOW [GLOBAL] STATUS or SHOW VARIABLES. The following is an explanation of them:

Thread Cache Hit Rate
(1 - (Threads_created / Connections)) * 100
When an application connects to a MySQL database, the database has to create a thread to manage the connection and the queries that will be sent in that connection. The database instructs the kernel to create a new thread, and the kernel allocates resources and creates the thread, then returns it to the MySQL service. When the connection is terminated by the application, MySQL tells the kernel to destroy the thread and free the resources. This create/destroy mechanism causes considerable overhead if the MySQL server has many new connections per second.
If MySQL doesn't destroy the thread when the connection is terminated, but reuses it and assigns it to the next connection then this will decrease the kernel overhead. This is why a high Thread Cache Hit Rate improves MySQL performance and decreases the system's CPU usage.
Setting the parameter thread_cache_size in the my.cnf file accordingly will help to correctly balance between having a great thread cache and keeping MySQL memory consumption reasonable.
Higher is better.

Query Cache Hit Rate
Qcache_hits / (Qcache_hits + Com_select) * 100
Higher should be considered better.
A query cache size increase is recommended if the query cache usage is very close to 100% and the query cache hit rate is far from 100%. But sometimes a size increase will not lead to a better hit rate: this means that the increase was not needed and that the application do not run enough cacheable SELECT queries.
This value should grow proportionally with the number of executed queries as long as the query cache is performing well. Please also have a look at the Query cache usage percentage to know if your query_cache configuration is appropriate.

For more information please refer to http://www.databasejournal.com/features/mysql/article.php/3808841/Optimizing-the-MySQL-Query-Cache.htm

Query Cache Usage
(1 - (Qcache_free_memory / query_cache_size)) * 100
This value should be reasonably far from 100%, otherwise consider incrementing the query_cache_size parameter in my.cnf.

Connections Usage
(Max_used_connections / max_connections) * 100
This value should be reasonably far from 100%, otherwise consider incrementing the max_connections parameter in my.cnf.

Key Buffer Usage
(Key_blocks_used / (Key_blocks_used + Key_blocks_unused)) * 100
This value should be reasonably far from 100%, otherwise consider incrementing the key_buffer_size parameter in my.cnf.

InnoDB Buffer Pool Usage
(1 - (Innodb_buffer_pool_pages_free / Innodb_buffer_pool_pages_total)) * 100
This value should be reasonably far from 100%, otherwise consider incrementing the innodb_buffer_pool_size parameter in my.cnf.

Temp. Tables To Disk
(Created_temp_disk_tables / Created_temp_disk_tables + Created_temp_tables)) * 100
During operation, MySQL has to create some temporary tables (that can be explicit, so created by the web application, or implicit, so for example MySQL has to create one when he runs some "SELECT DISTINCT", "UNION" or "VIEW" queries). MySQL will prefer to save this tmp tables to memory, for a fast access. But if tmp_table_size gets saturated, he has to write them on the disk instead, making the access slower.
Note that if you modify the value of tmp_table_size in the MySQL configuration file, you should also modify the value of max_heap_table_size as well, since both values should have the same value because MySQL uses the minimum of both, so raising one of them is useless.
Therefore this value helps to know how many tmp tables go to the disk instead than to the memory. Keep in mind that some large queries, involving TEXT and BLOB columns, are directly written to the disk instead than to the memory, because they would be too big. So you probably will want to avoid having a high % of tmp tables written to the disk, but you will never reach 0% on a big site, and this is fine.
Lower is better ... but 0% is not reachable and you should not try to reach it, usually.

Monitoring the Internet traffic of your LAN (traffacct.pm)

If your server acts as the gateway for a group of PCs, devices or even whole networks in your local LAN, you may want to know how much Internet traffic each one is generating.

This graph requires the iptables(8) command on GNU/Linux systems, and the ipfw command on *BSD systems.

The following are the options you will need to configure to accomplish all of this.

enabled

This option enables this feature.

Default value: n

max

This is the number of LAN devices you want to monitor. There is no limit, but keep in mind that every time this number changes, Monitorix will resize the traffacct.rrd file, removing all historical data.

Default value: 10

graphs_per_row

If your horizontal screen resolution is pretty wide, you may want to increase the number of graphs that appear on each row.

Default value: 2

list

This is a comma-separated list of names of PCs, LAN devices or whole networks that you want to monitor. The only requirement is that all they must utilize this server as their gateway.

If the names in this list are able to be resolved by a DNS query then you don't need to define the desc list (below) with corresponding IP addresses, unless you want monthly reports.

An example would be:

list = pc8, printer, pc9, scanner

desc

This is the list of IPv4 or IPv6 addresses with network masks and email addresses corresponding to the entries defined in the list. This option is only used when the those entries are not resolvable through a DNS query.

An example would be:

<desc>
0 = 192.168.1.101/32, ace@example.com
1 = 192.168.1.102/32, gene@example.com
2 = 192.168.1.103/32, paul@example.com
3 = 2607:6300:93:1::/64, peter@example.com
</desc

Monthly reports of Internet traffic (traffacct.pm)

enabled

If this option is set to y, Monitorix will send a report of all the monthly Internet activity of the defined devices in list to the specified email address on the first day of each month.

Default value: n

language

Define here the language used in the monthly report.

The current possible values are: ca, de, en, it, nl_NL, pl and zh_CN.

Default value: en

default_mail

This is the default email address used to send the monthly reports. This option is only used if the second parameter in desc list is empty.

Default value: root@localhost

url_prefix

This is the prefix of the same URL you use to connect to Monitorix. This is needed in order to get the graphs of the same machine.

Default value: http://localhost:8080

smtp_hostname

This is the hostname that will be used as a SMTP relay to deliver the monthly report emails.

Default value: localhost

from_address

This is the address that will be used as remittent for all the monthly report emails.

Default value: noreply@example.com

Monitoring remote servers (Multihost)

The Multihost feature allows you to monitor an unlimited number of remote servers that already have Monitorix installed. Make sure that all servers (local and remote) have the same version of Monitorix, otherwise there would be some incompatibilities that would prevent showing correctly the graphs.

enabled

This option enables the Multihost feature.

Default value: n

footer_url

If set to y Monitorix will show the original URL of each server at the bottom of the graph. Where security is important you may want to hide this information.

Default value: y

graphs_per_row

If your horizontal screen resolution is pretty wide, you may want to increase the number of graphs that appear on each row.

Default value: 2

default_option_when_all

If the user has defined a considerable amount of remote servers and it selects the option "All" in the Hostname list and "All graphs" in the Graph list, the browser may hang for a while due to the huge amount of images to download remotely from different servers.

This option prevents precisely that this happens accidentally by setting a default value in the Graph list. Of course, the user is able to change it to "All graphs" at any moment.

The value of this option may be any of the ones that appear in the <graphs> section (near the end) of the monitorix.conf file.

Default value: "System load"

remotehost_list

This is a comma-separated list with descriptive names of remote servers with Monitorix already installed and working that you plan to monitor from here.

An example of this list would be:

remotehost_list = server 1, server 2, server 3

remotehost_desc

This is a numbered list that describes each of the names defined in the remotehost_list option and the remote values of base_url and base_cgi options.

An example would be:

<remotehost_desc>
0 = http://www.example.com,/monitorix,/monitorix-cgi
1 = http://10.0.0.1,/monitorix,/monitorix-cgi
2 = http://192.168.0.100:8080,/,/
</remotehost_desc>

As you can see all these three entries use URLs to designate the location of each remote server. This means that each server most also have been enabled the HTTP built-in server, or have been installed a CGI capable web server like Apache.

groups

This enables the server grouping for those environments where there are too much servers to display at the same time. Hence, you can group them in order to show them separately.

Default value: n

remotegroup_list

This is a list of groups of remote servers with Monitorix already installed and working that you plan to monitor from here.

An example of this list would be:

remotegroup_list = My Group

remotegroup_desc

This is a numbered list that describes each of the names defined in the remotegroup_list option.

An example would be:

<remotegroup_desc>
0 = server2, server 3
</remotegroup_desc>

Automatic email reports (emailreports)

This allows one to send automatically selected graphs to one or more email addresses. This could be specially useful for some system administrators who prefer receiving via email selected graphs instead of browsing to the remote servers every day.

enabled

This option enables this feature. Note that you still need to enable the same option for each time interval you want to activate: daily, weekly, monthly, yearly.

Default value: n

url_prefix

This is the prefix of the same URL you use to connect to Monitorix. Such URL is needed in order to get the graphs of that machine.

This option supports sending the credentials in the standard HTTP "Authorization" header, just like this:

http://username:password@localhost:8080

Default value: http://localhost:8080

smtp_hostname

This is the hostname that will be used as a SMTP relay to deliver the automatic email reports.

method

This option specifies the method of sending emails. The current valid options are smtp and relay. By default this option is not defined which is the same as if smtp option was defined.

Default value:

from_address

This is the address that will be used as remittent for all the monthly report emails.

Default value: noreply@example.com

subject_prefix

This is a string that will be prefixed in the Subject of all emails that will be sent.

Default value: Monitorix:

hour

This is the hour (in 24h format) when the email reports will be sent.

Default value: 0

minute

This is the minute when the email reports will be sent.

Default value: 0

daily
weekly
monthly
yearly

The email reports are sent based on the following schedule:

daily reports will be sent every day at 00:00h.
weekly reports will be sent the first Monday of each week.
monthly reports will be sent the first day of each month.
yearly reports will be sent the first day of each year.

enabled

This option enables each report individually.

Default value: n

graphs

This is a comma-separated list of graph names you want to appear in the email report. The names are the same as their .rrd files. There is a list of them in the graph_name option in monitorix.conf.

Default value: system, fs

This is a comma-separated list of recipient email addresses.

addendum_script

This is the full path name of an external script that will be executed during the creation of the report, and its output will be appended to the mail. This is useful for system administrators that want to add extra system information to the reports.

Default value:

rigid and limit values

rigid

This value defines how the graph must be scaled. Its possible values are:

0 No rigid, the graph will be scaled automatically. Only the lower-limit value will be used if it's defined.
1 The graph will be scaled by default according the values in limit but without rigidness.
2 The graph will be forced to scale using the contents of limit as its upper-limit and lower-limit values.

limit

This is where you can enter the upper-limit and lower-limit values (separated by a colon) for a graph. The lower-limit value is optional. Some examples would be:

100:0 which means 100 as the upper-limit value and 0 for the lower-limit value. This is commonly used for percentage values.
1000 which means 1000 as the upper-limit value and leaving undefined the lower-limit value. This can also be written as 1000:.
