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,  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.

   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:

       -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 pcp2graphite.  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 archive argument, 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.

       -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.

       --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).

       -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=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).  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 ranked 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.
            Ranking does not imply sorting, see -6.  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.   Ranking  does
            not imply sorting, see -6.

            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, --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.

       -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 samples argument 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
            Set  the  reporting  interval  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

       pcp2graphite.conf
            pcp2graphite configuration file (see -c)

PCP ENVIRONMENT

       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).
