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


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


       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 accepted:

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

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

       -n pmnsfile
              Load an alternative Performance  Metrics  Name  Space  (pmns(4))
              from the file pmnsfile.

       -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 $PCP_VAR_DIR/config/pmlogger/config.pcp.

       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 subdirectory, otherwise the full
       pathname is displayed (the  PCP  log  rotation  and  periodic  pmlogger
       checking   facilities   support   the   creation   of   archives  below

       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  configuration
       file, as described in pcp.conf(4).


       PCPIntro(1), pmcd(1), pmie(1), pmlogger(1), pcp.conf(4) and pcp.env(4).


       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.
