       pminfo - display information about performance metrics


       pminfo  [-dfFLmMtTvxz] [-a archive] [-b batchsize] [-c dmfile] [-h hostname] [-K spec] [-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 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
       Performance  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
            configuration 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
            conforms  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
            timezone  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
            processed  that is of type PM_TYPE_EVENT, then the event records will be unpacked and
            the details of each event record reported.

       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(4).
