DESCRIPTION         top

       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).

       Only the command line options listed on this page are supported,
       other options recognized by pmrep(1) are not supported.

       Configuration file options override the corresponding built-in
       default values (if any).  Command line options override the
       corresponding configuration file options (if any).

CONFIGURATION FILE         top

       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, ignore_incompat, instances, omit_flat, precision,
       count_scale, space_scale, time_scale.  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..

COMMAND LINE OPTIONS         top

       The available command line options are:

       -a   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 (see
            mkaf(1)).

       -A   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   Unit/scale for space (byte) metrics, possible values include
            bytes, Kbytes, KB, Mbytes, MB, and so forth up to Ebytes, EB.
            This option will not override possible per-metric
            specifications.  See also pmParseUnitsStr(3).

       -c   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   Exit before reporting any values, but after parsing the
            configuration and metrics and printing possible headers.

       --daemonize
            Daemonize on startup.

       -e   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-separated derived metric expressions.  For
            details see pmLoadDerivedConfig(3) and pmRegisterDerived(3).

       -E   Graphite server plaintext port.  Using this option disables the
            pickle protocol.

       -g   Graphite server to send the metrics to.

       -G   Do not include global metrics in reporting (see pmrep.conf(5)).

       -h   Fetch performance metrics from pmcd(1) on host, rather than the
            default localhost.

       -H   Do not print any headers.

       -i   Report only the listed instances (if present).  By default all
            current instances 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
            metrics without instances are reported as usual, use -v to
            change this.  Please refer to pmrep(1) for more details on this
            option.

       -I   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.

       -K   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   Use a local context to collect metrics from DSO PMDAs on the
            local host without PMCD.  See also -K.

       -O   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   Graphite server pickle port.  Using this option enables the
            pickle protocol.

       -P   Use precision for numeric non-integer output values.  The
            default is to use 3 decimal places (when applicable).

       -q   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).

       -r   Output raw metric values, do not convert cumulative counters to
            rates.  This option will override possible per-metric
            specifications.

       -s   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   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   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   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 single-valued ``flat'' metrics from reporting when
            instances were requested.  See -i and -I.

       -V   Display version number and exit.

       -x   Metrics prefix for measurements sent to the server.

       -X   Pickle protocol version number.

       -y   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).

       -?   Display usage message and exit.

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to parametrize
       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).
