Logwatch is a customizable, pluggable log-monitoring
system. It will go through your logs for a given period of time and make a
report in the areas that you wish with the detail that you wish. Logwatch is
being used for Linux and many types of UNIX.
- --detail
level
- This is the detail level of the report. level can be a positive
integer, or high, med, low, which correspond to the integers 10, 5, and 0,
respectively.
- --logfile
log-file-group
- This will force Logwatch to process only the set of logfiles defined by
log-file-group (i.e. messages, xferlog, ...). Logwatch will
therefore process all services that use those logfiles. This option can be
specified more than once to specify multiple logfile-groups.
- --service
service-name
- This will force Logwatch to process only the service specified in
service-name (i.e. login, pam, identd, ...). Logwatch will
therefore also process any log-file-groups necessary to process these
services. This option can be specified more than once to specify multiple
services to process. A useful service-name is All which will
process all services (and logfile-groups) for which you have filters
installed.
- --mailto
address
- Mail the results to the email address or user specified in
address.
- --range
range
- You can specify a date-range to process. Common ranges are Yesterday,
Today, All, and Help. Additional options are listed when
invoked with the Help parameter.
- --archives
- Each log-file-group has basic logfiles (i.e. /var/log/messages) as well as
archives (i.e. /var/log/messages.? or /var/log/messages.?.gz). When used
with "--range all", this option will make Logwatch search
through the archives in addition to the regular logfiles. For other values
of --range, Logwatch will search the appropriate archived logs.
- --debug
level
- For debugging purposes. level can range from 0 to 100. This will
really clutter up your output. You probably don't want to use
this.
- --filename
file-name
- Save the output to file-name instead of displaying or mailing
it.
- --logdir
directory
- Look in directory for log subdirectories or log files first before
looking in the default directories.
- --hostlimit
host1,host2
- Limit report to hostname - host1, host2.
- --hostname
hostname
- Use hostname for the reports instead of this system's hostname. In
addition, if HostLimit is set in the logwatch.conf configuration file (see
MORE INFORMATION, below), then only logs from this hostname will be
processed (where appropriate).
- --html_wrap
num-characters
- Number of characters that html output should be wrapped to. Default is
80.
- --hostformat
split
- Use split approach when formatting report for multiple hosts - none
[default], split, splitmail.
- --output
output-type
- Report using output-type - stdout [default], mail, file.
- --format
format
- Format report using format - text [default], html.
- --encode
encoding
- Encode report using encoding - none [default], base64.
- --numeric
- Inhibits additional name lookups, displaying IP addresses
numerically.
- --usage
- Displays usage information
- --help
- same as --usage.
- /usr/share/logwatch/
This directory contains all the perl executables and
configuration files shipped with the logwatch distribution.
- /etc/logwatch
This directory contains local configuration files that
override the default configuration. See MORE INFORMATION below for more
information.
logwatch --service ftpd-xferlog --range all --detail high
--archives
This will print out all FTP transfers that are stored in
all current and archived xferlogs.
logwatch --service pam_pwdb --range yesterday --detail high
This will print out login information for the previous
day...
The directory /usr/share/doc/logwatch-* contains several files
with additional documentation:
HOWTO-Customize-LogWatch
Documents the directory structure of Logwatch
configuration and executable files, and describes how to customize Logwatch by
overriding these default files.
LICENSE
Describes the License under which Logwatch is
distributed. Additional clauses may be specified in individual files.
README
Describes how to install, where to find it, mailing
lists, and other useful information.
