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  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, 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  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.   Labels  are,
           however, omitted for backward compatibility, use include_labels yes to include them as
           well.  Corresponding command line option is -X.  Default is 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 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 or directory to use.  In case config is a directory all files
            under  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  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
            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 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

       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).
