       pmdasummary - summary performance metrics domain agent (PMDA)


       $PCP_PMDAS_DIR/summary/pmdasummary  [-d  domain]  [-h helpfile] [-l logfile] [-U username]


       pmdasummary is a Performance Metrics Domain Agent (PMDA) which derives performance metrics
       values from values made available by other PMDAs.  pmdasummary consists of two processes:

       pmie process
              The  inference engine for performance values pmie(1) is used to periodically sample
              values for the base metrics and  compute  the  derived  values.   This  process  is
              launched  with the given pmie-command-line arguments by the main process, described

       main process
              The main process reads and buffers the values computed by pmie(1)  and  makes  them
              available to the performance metrics collector daemon pmcd(1).

       A brief description of the pmdasummary command line options follows:

       -d   It is absolutely crucial that the performance metrics domain number specified here is
            unique and consistent.  That is, domain should be different for every PMDA on the one
            host, and the same domain number should be used for the same PMDA on all hosts.

       -h   This  option  specifies  an  alternative  help  text file helpfile for describing the
            metrics that pmdasummary represents.

       -l   Location of the log file.  By default, a log file named summary.log is written in the
            current  directory  of  pmcd(1) when pmdasummary is started, i.e.  $PCP_LOG_DIR/pmcd.
            If the log file cannot be created or is  not  writable,  output  is  written  to  the
            standard error instead.

       -U   User  account  under  which  to run the agent.  The default is the unprivileged "pcp"
            account in current versions of PCP, but  in  older  versions  the  superuser  account
            ("root") was used by default.


       If you want access to the names, help text and values for the summary performance metrics,
       do the following as root:

            # cd $PCP_PMDAS_DIR/summary
            # ./Install

       If you want to undo the installation, do the following as root:

            # cd $PCP_PMDAS_DIR/summary
            # ./Remove

       pmdasummary is launched by pmcd(1) and should never be executed directly.  The Install and
       Remove scripts notify pmcd(1) when the agent is installed or removed.


                 command line options used to launch pmdasummary
                 default pmie(1) expressions defining the summary metrics
                 default help text for the summary metrics
                 installation script for the pmdasummary agent
                 undo installation script for the pmdasummary agent
                 default log file for error messages and other information from pmdasummary


       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).
