DESCRIPTION
pcp2graphite is a customizable performance metrics exporter tool from PCP to Graphite. 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.
pcp2graphite is a close relative of pmrep(1). Please refer to pmrep(1) for the metricspec description
accepted on pcp2graphite command line and pmrep.conf(5) for description of the pcp2graphite.conf
configuration file overall syntax, this page describes pcp2graphite specific options and configuration
file differences with pmrep.conf(5). pmrep(1) also lists some usage examples of which most are
applicable with pcp2graphite 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).
CONFIGURATION FILE
pcp2graphite 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, 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. pcp2graphite specific options graphite_host (string) Hostname or IP address of Graphite server to send the metrics to. Corresponding command line option is -g. Default is localhost. graphite_port (integer) Specify port number of Graphite server (plaintext or pickle). Corresponding command line options are -p and -E. Default is 2004. pickle (boolean) Specify whether to use pickle protocol. Corresponding command line options are -p and -E. Default is yes. pickle_protocol (integer) Specify pickle protocol version. Corresponding command line option is -X. Default is 0. prefix (string) Specify the prefix for metrics sent to the server. Corresponding command line option is -x. Default is pcp..
OPTIONS
The available command line options are:
-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
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: ./pcp2graphite.conf,
$HOME/.pcp2graphite.conf, $HOME/pcp/pcp2graphite.conf, and $PCP_SYSCONF_DIR/pcp2graphite.conf. For
details, see the above section and pmrep.conf(5).
--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 port, --text-port=port
Graphite server plaintext port. Using this option disables the pickle protocol.
-g server, --graphite-host=server
Graphite 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 pcp2graphite 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.
-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). Doing live filtering over a huge amount of
instances naturally comes with some overhead so a bit of user caution is advised.
-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 filter 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 predicate filter reference metrics, ranking is done only
for the specified metrics. When reporting, the rest of the metrics sharing the same instance domain
(see PCPIntro(1)) as the predicates will include only the highest/lowest ranking instances of the
corresponding predicates.
So for example, when the using proc.memory.rss (resident size of process) as the predicate and
including proc.io.total_bytes and mem.util.used as metrics to be reported, only the processes using
most/least memory (as per -J) 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, --pickle-port=port
Graphite server pickle port. Using this option enables the pickle protocol.
-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.
-0 precision, --precision-force=precision
Like -P but this option will override 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, pcp2graphite 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 pcp2graphite 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 pcp2graphite 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, --prefix=prefix
Metrics prefix for measurements sent to the server.
-X protocol, --pickle-protocol=protocol
Pickle protocol version number.
-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.
FILES
