       pminfo - display information about performance metrics

       pminfo  [-dfFLmMtTvxz]  [-a  archive]  [-b  batchsize] [-c dmfile] [-h hostname] [-K spec]
       [-[n|N] pmnsfile] [-O time] [-Z timezone] [metricname ...]

       pminfo displays various types of information about performance metrics  available  through
       the facilities of the Performance Co-Pilot (PCP).

       Normally pminfo operates on the distributed Performance Metrics Name Space (PMNS), however
       if the -n option is specified an alternative local PMNS is loaded from the file	pmnsfile.
       The  -N option supports the same function as -n, except for the handling of duplicate Per-
       formance Metric Identifiers (PMIDs) in pmnsfile - duplicates are allowed with -N they  are
       not allowed with -n.

       The  metrics  of  interest are named in the metricname arguments.  If metricname is a non-
       leaf node in the PMNS, then pminfo will recursively descend the PMNS  and  report  on  all
       leaf nodes.  If no metricname argument is given, the root of the PMNS is used.

       Unless  directed to another host by the -h option, by default pminfo will contact the Per-
       formance Metrics Collector Daemon (PMCD) on the local host.  The connection to a  PMCD  is
       only required if pminfo requires distributed PMNS information, and/or meta-data describing
       metrics, and/or metric values, and/or help text.

       The -a option causes pminfo to use the specified archive rather than connecting to a PMCD.
       The -a , -h and -L options are mutually exclusive.

       The  -L	option	causes pminfo to use a local context to collect metrics from PMDAs on the
       local host without PMCD.  Only some metrics are available in this mode.	The -a,-h and  -L
       options are mutually exclusive.

       The -b option may be used to define the maximum size of the group of metrics to be fetched
       in a single request for the -f and -v options.  The default value for batchsize is 20.

       Other options control the specific information to be reported.

       -c   The dmfile argument specifies a file that contains derived metric definitions in  the
	    format  described  for  pmLoadDerivedConfig(3).  The -c option provides a way to load
	    derived metric definitions that is an alternative to the  more  generic  use  of  the
	    PCP_DERIVED_CONFIG	environment  variable  as described in PCPIntro(1).  Using the -c
	    option and the PCP_DERIVED_CONFIG environment variable to specify the same configura-
	    tion is a bad idea, so choose one or the other method.

       -d   Metric  descriptions  detailing the PMID, data type, data semantics, units, scale and
	    associated instance domain.

       -f   Fetch and print values for all instances.  When fetching from an archive, only  those
	    instances  present	in  the  first archive record for a metric will be displayed; see
	    also the -O option, else use pmdumplog(1) which may be a better  tool  for	examining

       -F   Same  as  -f  but try harder to fetch instances for metrics which have non-enumerable
	    instance domains (e.g. metrics in the ``proc'' subtree of the default PMNS).

       -K   When using the -L option to fetch metrics from a local context, the -K option may  be
	    used to control the DSO PMDAs that should be made accessible.  The spec argument con-
	    forms to the syntax described in __pmSpecLocalPMDA(3).  More than one -K  option  may
	    be used.

       -m   Print the PMID in terse mode.

       -M   Print the PMID in verbose mode.

       -O   When  used in conjunction with an archive source of metrics and the options -f or -F,
	    the time argument defines a time origin at which the metrics should be  fetched  from
	    the archive.  Refer to PCPIntro(1) for a complete description of this option, and the
	    syntax for the time argument.

	    When the ``ctime'' format is used for the time argument in a -O option, the  timezone
	    becomes  an  issue.   The  default	is  to use the local timezone on the system where
	    pminfo is run.  The -Z option changes the timezone to timezone in the format  of  the
	    environment  variable TZ as described in environ(5).  The -z option changes the time-
	    zone to the local timezone at the host that is the source of the performance metrics,
	    as identified via the -a option.

       -t   Print the ``one line'' help summary, if available.

       -T   Print the help text, if available.

       -v   Verify mode in which descriptions and values are retrieved, but only error conditions
	    are reported.  This option silently disables any output from the options -f, -M,  -m,
	    -t and -T.

       -x   Like  the  -f  option,  but with the additional functionality that if a value is pro-
	    cessed that is of type PM_TYPE_EVENT, then the event records will be unpacked and the
	    details of each event record reported.

		 default local PMNS specification files

       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 config-
       uration file, as described in pcp.conf(5).
