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).  Refer to pmrep(1) for the metricspec description
       accepted on pcp2xml command line.  See pmrep.conf(5) for description of  the  pcp2xml.conf
       configuration file 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 available
       for 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 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,
       include_labels,  precision,  precision_force, count_scale, count_scale_force, space_scale,
       space_scale_force, time_scale, time_scale_force.  The rest of the pmrep.conf  options  are
       recognized but ignored for compatibility.

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

       everything (boolean)
           Write everything known  about  metrics,  including  PCP  internal  IDs.   Labels  are,
           however, omitted for backward compatibility.  Enable include_labels to include them as
           well.  Corresponding command line option is -X.  Defaults to no.

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 pcp2xml.  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 occurs).

       -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 or directory to use.  In case config is a directory all files
            in  it  ending  .conf  will  be  included.   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=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 PCP  derived  metrics  configuration  file,
            otherwise  it  will  be  interpreted  as comma- or semicolon-separated derived metric
            expressions.  For complete description of derived metrics  and  PCP  derived  metrics
            configuration    files    see    pmLoadDerivedConfig(3)   and   pmRegisterDerived(3).
            Alternatively, using  pmrep.conf(5)  configuration  syntax  allows  defining  derived
            metrics as part of metricsets.

       -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
            Retrieve and report only the specified metric instances.  By default  all  instances,
            present and future, are reported.

            Refer to pmrep(1) for complete description of 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 named instances even if
            processes are restarted at some point (unlike without  live  filtering).   Performing
            live  filtering  over a huge number 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.

       -m, --include-labels
            Include PCP metric labels in the output.

       -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 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, 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
            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 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
            Report only set-valued metrics with instances (e.g. disk.dev.read) and  omit  single-
            valued ``flat'' metrics without instances (e.g.  kernel.all.sysfork).  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.  Labels are,
            however, omitted for backward compatibility, use -m to include them as well.

       -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

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).
