pcp2zabbix is a customizable performance metrics exporter
tool from PCP to Zabbix. Any available performance metric, live or archived,
system and/or application, can be selected for exporting using either
command line arguments or a configuration file.
pcp2zabbix is a close relative of pmrep(1). Please
refer to pmrep(1) for the metricspec description accepted on
pcp2zabbix command line and pmrep.conf(5) for description of
the pcp2zabbix.conf configuration file overall syntax, this page
describes pcp2zabbix specific options and configuration file
differences with pmrep.conf(5). pmrep(1) also lists some usage
examples of which most are applicable with pcp2zabbix as well.
Only the command line options listed on this page are supported,
other options recognized by pmrep(1) are not supported.
Options via environment values (see pmGetOptions(3))
override the corresponding built-in default values (if any). Configuration
file options override the corresponding environment variables (if any).
Command line options override the corresponding configuration file options
(if any).
pcp2zabbix uses a configuration file with overall syntax
described in pmrep.conf(5). The following options are common with
pmrep.conf: version, source, speclocal,
derived, header, globals, samples,
interval, type, type_prefer, ignore_incompat,
names_change, instances, live_filter, rank,
limit_filter, limit_filter_force, invert_filter,
predicate, omit_flat, precision,
precision_force, count_scale, count_scale_force,
space_scale, space_scale_force, time_scale,
time_scale_force. The output option is recognized but ignored
for pmrep.conf compatibility.
zabbix_server (string)
Hostname or IP address of Zabbix server to send the
metrics to. If a host is monitored by a proxy, proxy hostname or IP address
should be used instead. Corresponding command line option is -g.
Default is localhost.
zabbix_port (integer)
Specify port number of server trapper running on the
server. Corresponding command line option is -p. Default is
10051.
zabbix_host (string)
Specify agent hostname as registered in Zabbix frontend.
Host IP address and DNS name will not work. Corresponding command line option
is -X. Defaults to the metrics source host.
zabbix_interval (string)
Indicates the interval to send the metrics to the Zabbix
server. This can be longer than the generic
interval to minimize the
overhead when communicating with the server (as each send creates a new
connection). Follows the time syntax described in
PCPIntro(1).
Corresponding command line option is
-E. Defaults to the generic
interval. Zabbix tools send at most 250 metrics at a time. Ignored when
reading metrics from PCP archives, in which case metrics will be sent roughly
at 250 metric batches.
zabbix_prefix (string)
Specify the prefix for metrics sent to the Zabbix server.
Corresponding command line option is -x. Default is .pcp.
zabbix_lld (boolean)
Specify whether to enable Zabbix low-level discovery.
Corresponding command line option is -l. Default is no.
The available command line options are:
- -0 precision, --precision-force=precision
- Like -P but this option will override per-metric
specifications.
- -4 action, --names-change=action
- Specify which action to take on receiving a metric names change
event during sampling. These events occur when a PMDA discovers new
metrics sometime after starting up, and informs running client tools like
pcp2zabbix. Valid values for action are update
(refresh metrics being sampled), ignore (do nothing - the default
behaviour) and abort (exit the program if such an event
happens).
- -5, --ignore-unknown
- Silently ignore any metric name that cannot be resolved. At least one
metric must be found for the tool to start.
- -8 limit, --limit-filter=limit
- Limit results to instances with values above/below limit. A
positive integer will include instances with values at or above the limit
in reporting. A negative integer will include instances with values at or
below the limit in reporting. A value of zero performs no limit filtering.
This option will not override possible per-metric specifications.
See also -J and -N.
- -9 limit, --limit-filter-force=limit
- Like -8 but this option will override per-metric
specifications.
- -a archive,
--archive=archive
- Performance metric values are retrieved from the set of Performance
Co-Pilot (PCP) archive log files identified by the argument
archive, which is a comma-separated list of names, each of which
may be the base name of an archive or the name of a directory containing
one or more archives.
- --archive-folio=folio
- Read metric source archives from the PCP archive folio created by
tools like pmchart(1) or, less often, manually with
mkaf(1).
- -A align,
--align=align
- Force the initial sample to be aligned on the boundary of a natural time
unit align. Refer to PCPIntro(1) for a complete description
of the syntax for align.
- -b scale,
--space-scale=scale
- Unit/scale for space (byte) metrics, possible values include
bytes, Kbytes, KB, Mbytes, MB, and so
forth. This option will not override possible per-metric
specifications. See also pmParseUnitsStr(3).
- -B scale,
--space-scale-force=scale
- Like -b but this option will override per-metric
specifications.
- -c config,
--config=config
- Specify the config file to use. The default is the first found of:
./pcp2zabbix.conf,
$HOME/.pcp2zabbix.conf,
$HOME/pcp/pcp2zabbix.conf, and
$PCP_SYSCONF_DIR/pcp2zabbix.conf. For
details, see the above section and pmrep.conf(5).
- --container=container
- Fetch performance metrics from the specified container, either
local or remote (see -h).
- -C, --check
- Exit before reporting any values, but after parsing the configuration and
metrics and printing possible headers.
- --daemonize
- Daemonize on startup.
- -e derived,
--derived=derived
- Specify derived performance metrics. If derived starts with
a slash (``/'') or with a dot (``.'') it will be interpreted as a derived
metrics configuration file, otherwise it will be interpreted as comma- or
semicolon-separated derived metric expressions. For details see
pmLoadDerivedConfig(3) and pmRegisterDerived(3).
- -E interval,
--zabbix-interval=interval
- Specify the interval to send metrics to the server. See
zabbix_interval description above for details.
- -g server,
--zabbix-server=server
- Zabbix server to send the metrics to.
- -G,
--no-globals
- Do not include global metrics in reporting (see
pmrep.conf(5)).
- -h host,
--host=host
- Fetch performance metrics from pmcd(1) on host, rather than
from the default localhost.
- -H,
--no-header
- Do not print any headers.
- -i instances,
--instances=instances
- Report only the listed instances from current instances (if
present, see also -j). By default all instances, present and
future, are reported. This is a global option that is used for all metrics
unless a metric-specific instance definition is provided as part of a
metricspec. By default single-valued ``flat'' metrics without
multiple instances are still reported as usual, use -v to change
this. Please refer to pmrep(1) for more details on this
option.
- -I,
--ignore-incompat
- Ignore incompatible metrics. By default incompatible metrics (that is,
their type is unsupported or they cannot be scaled as requested) will
cause pcp2zabbix to terminate with an error message. With this
option all incompatible metrics are silently omitted from reporting. This
may be especially useful when requesting non-leaf nodes of the PMNS tree
for reporting.
- -l,
--zabbix-lld
- Add low-level discovery (LLD) metrics. This allows PCP metric instance
domains to be sent to Zabbix, so that prototype items/triggers/graphs may
be automatically constructed by Zabbix. For each PCP metric with an
instance domain, the key pcp.discovery[pcp.met.ric] is sent
periodically. This symbol should be added to a discovery rule, and will
define the {#PCP.MET.RIC} LLD macro. This macro can inturn be used
to define prototype items/triggers/graphs. The names are adjusted if
-x was given to override the pcp. prefix.
- -j,
--live-filter
- Perform instance live filtering. This allows capturing all filtered
instances even if processes are restarted at some point (unlike without
live filtering). Performing live filtering over a huge amount of instances
will add some internal overhead so a bit of user caution is advised. See
also -n.
- -J rank,
--rank=rank
- Limit results to highest/lowest rank instances of set-valued
metrics. A positive integer will include highest valued instances in
reporting. A negative integer will include lowest valued instances in
reporting. A value of zero performs no ranking. See also -8.
- -K spec,
--spec-local=spec
- When fetching metrics from a local context (see -L), the -K
option may be used to control the DSO PMDAs that should be made
accessible. The spec argument conforms to the syntax described in
pmSpecLocalPMDA(3). More than one -K option may be
used.
- -L,
--local-PMDA
- Use a local context to collect metrics from DSO PMDAs on the local host
without PMCD. See also -K.
- -n,
--invert-filter
- Perform ranking before live filtering. By default instance live filtering
(when requested, see -j) happens before instance ranking (when
requested, see -J). With this option the logic is inverted and
ranking happens before live filtering.
- -N predicate,
--predicate=predicate
- Specify a comma-separated list of predicate filter reference
metrics. By default ranking (see -J) happens for each metric
individually. With predicates, ranking is done only for the specified
predicate metrics. When reporting, rest of the metrics sharing the same
instance domain (see PCPIntro(1)) as the predicate will
include only the highest/lowest ranking instances of the corresponding
predicate.
So for example, using proc.memory.rss (resident memory size
of process) as the predicate metric together with
proc.io.total_bytes and mem.util.used as metrics to be
reported, only the processes using most/least (as per -J) memory will
be included when reporting total bytes written by processes. Since
mem.util.used is a single-valued metric (thus not sharing the same
instance domain as the process-related metrics), it will be reported as
usual.
- -O origin,
--origin=origin
- When reporting archived metrics, start reporting at origin within
the time window (see -S and -T). Refer to PCPIntro(1)
for a complete description of the syntax for origin.
- -p port,
--zabbix-port=port
- Zabbix server port number.
- -P precision,
--precision=precision
- Use precision for numeric non-integer output values. The default is
to use 3 decimal places (when applicable). This option will not
override possible per-metric specifications.
- -q scale,
--count-scale=scale
- Unit/scale for count metrics, possible values include count x
10^-1, count, count x 10, count x 10^2, and so
forth from 10^-8 to 10^7. (These values are currently
space-sensitive.) This option will not override possible per-metric
specifications. See also pmParseUnitsStr(3).
- -Q scale,
--count-scale-force=scale
- Like -q but this option will override per-metric
specifications.
- -r, --raw
- Output raw metric values, do not convert cumulative counters to rates.
This option will override possible per-metric specifications.
- -R,
--raw-prefer
- Like -r but this option will not override per-metric
specifications.
- -s samples,
--samples=samples
- The argument samples defines the number of samples to be retrieved
and reported. If samples is 0 or -s is not specified,
pcp2zabbix will sample and report continuously (in real time mode)
or until the end of the set of PCP archives (in archive mode). See also
-T.
- -S starttime,
--start=starttime
- When reporting archived metrics, the report will be restricted to those
records logged at or after starttime. Refer to PCPIntro(1)
for a complete description of the syntax for starttime.
- -t interval,
--interval=interval
- The default update interval may be set to something other than the
default 1 second. The interval argument follows the syntax
described in PCPIntro(1), and in the simplest form may be an
unsigned integer (the implied units in this case are seconds). See also
the -T option.
- -T endtime,
--finish=endtime
- When reporting archived metrics, the report will be restricted to those
records logged before or at endtime. Refer to PCPIntro(1)
for a complete description of the syntax for endtime.
When used to define the runtime before pcp2zabbix will
exit, if no samples is given (see -s) then the number of
reported samples depends on interval (see -t). If
samples is given then interval will be adjusted to allow
reporting of samples during runtime. In case all of -T,
-s, and -t are given, endtime determines the actual
time pcp2zabbix will run.
- -v,
--omit-flat
- Omit single-valued ``flat'' metrics from reporting, only consider
set-valued metrics (i.e., metrics with multiple values) for reporting. See
-i and -I.
- -V, --version
- Display version number and exit.
- -x prefix,
--zabbix-prefix=prefix
- Metrics prefix for measurements sent to the server.
- -X hostname,
--zabbix-host=hostname
- Specify the agent hostname as registered in Zabbix frontend.
- -y scale,
--time-scale=scale
- Unit/scale for time metrics, possible values include
nanosec, ns, microsec, us, millisec,
ms, and so forth up to hour, hr. This option will
not override possible per-metric specifications. See also
pmParseUnitsStr(3).
- -Y scale,
--time-scale-force=scale
- Like -y but this option will override per-metric
specifications.
- -?, --help
- Display usage message and exit.
Environment variables with the prefix PCP_ are used to
parameterize the file and directory names used by PCP. On each installation,
the file /etc/pcp.conf contains the local values for these variables.
The $PCP_CONF variable may be used to specify an alternative
configuration file, as described in pcp.conf(5).
For environment variables affecting PCP tools, see
pmGetOptions(3).
