       pcp - summarize a Performance Co-Pilot (PCP) installation

       pcp [-p] [-a archive] [-h host] [-n pmnsfile]

       The  pcp  command summarizes the status of a Performance Co-Pilot (PCP) installation.  The
       report includes: the OS version, a summary of the hardware inventory, the local	timezone,
       details	of valid PCP licenses, the PCP software version, the state of the pmcd(1) process
       and associated Performance Metrics Domain Agents (PMDAs), as well as information about any
       PCP archive loggers (pmlogger(1)) and PCP inference engines (pmie(1)) that are running.

       For more general information about PCP, refer to PCPIntro(1).

       With  no  arguments,  pcp  reports  on  the  local host, however the following options are

       -a archive
	      Report the PCP configuration as described in the PCP archive log archive.

       -h host
	      Report the PCP configuration on host rather than the local host.

       -n pmnsfile
	      Load an alternative Performance Metrics Name Space (pmns(5)) from  the  file  pmns-

       -p     Display  pmie  performance information - counts of rules evaluating to true, false,
	      or indeterminate, as well as the expected rate of rule calculation, for  each  pmie
	      process  running on the default host.  Refer to the individual metric help text for
	      full details on these values.

       All of the displayed values are performance metric values and further information for each
       can be obtained using the command:

	  $ pminfo -dtT metric

       The  complete  set  of  metrics	required  by  pcp  to  produce its output is contained in

       When displaying running pmlogger instances, as a space-saving measure pcp will  display	a
       relative  path to the archive being created if that archive is located below a pcplog sub-
       directory, otherwise the full pathname is displayed (the PCP  log  rotation  and  periodic
       pmlogger  checking  facilities  support the creation of archives below $PCP_LOG_DIR/pmlog-

       A similar convention is used for trimming the amount of information displayed for  running
       pmie  instances,  where configuration files below $PCP_VAR_DIR/config will be displayed in
       truncated form.

		 pmlogger configuration file for collecting all of the metrics required by pcp.

       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).

       PCPIntro(1), pmcd(1), pmie(1), pmlogger(1), pcp.conf(5) and pcp.env(5).

       pcp  will  terminate  with  an  exit  status  of 1 if pmcd on the target host could not be
       reached or the archive could not be opened, or 2 for any other error.
