DESCRIPTION

       pcp2xml is a customizable performance metrics exporter tool from PCP to XML.  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.

       pcp2xml is a close relative of pmrep(1).   Please  refer  to  pmrep(1)  for  the  metricspec  description
       accepted on pcp2xml command line and pmrep.conf(5) for description of the pcp2xml.conf configuration file
       overall syntax, this page describes pcp2xml specific options  and  configuration  file  differences  with
       pmrep.conf(5).   pmrep(1)  also  lists  some  usage examples of which most are applicable with pcp2xml 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

       pcp2xml  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.

   pcp2xml specific options
       extended (boolean)
           Write extended information about metrics.  Corresponding command line option is -x.  Default is no.

       everything (boolean)
           Write everything known about metrics, including PCP internal IDs.  Corresponding command line  option
           is -X.  Default is no.

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:   ./pcp2xml.conf,
            $HOME/.pcp2xml.conf,  $HOME/pcp/pcp2xml.conf,  and  $PCP_SYSCONF_DIR/pcp2xml.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).

       -G, --no-globals
            Do not include global metrics in reporting (see pmrep.conf(5)).

       -f format, --timestamp-format=format
            Use the format string for  formatting  the  timestamp.   The  format  will  be  used  with  Python's
            datetime.strftime  method which is mostly the same as that described in strftime(3).  The default is
            %Y-%m-%d %H:%M:%S.

       -F outfile, --output-file=outfile
            Specify the output file outfile.

       -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 pcp2xml 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 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, pcp2xml 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 pcp2xml 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 pcp2xml 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, --with-extended
            Write extended information.

       -X, --with-everything
            Write everything known about metrics, including PCP internal IDs.

       -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.

       -z, --hostzone
            Use the local timezone of the host that is the source of the performance metrics, as  identified  by
            either the -h or the -a options.  The default is to use the timezone of the local host.

       -Z timezone, --timezone=timezone
            Use  timezone  for  the  date and time.  Timezone is in the format of the environment variable TZ as
            described in environ(7).  Note that when including a timezone string in output, ISO 8601 -style  UTC
            offsets are used (so something like -Z EST+5 will become UTC-5).

       -?, --help
            Display usage message and exit.

FILES

       pcp2xml.conf
              pcp2xml 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).
