NAME         top

       pmdapodman - podman container performance metrics domain agent (PMDA)

SYNOPSIS         top

       $PCP_PMDAS_DIR/podman/pmdapodman [-d domain] [-l logfile]

DESCRIPTION         top

       podman(1) is a utility for managing pods, containers and container
       images, following the container pod concept popularized by
       Kubernetes.  pmdapodman is a Performance Metrics Domain Agent (PMDA)
       which extracts performance metrics describing the state of containers
       and pods managed by podman.

       The podman PMDA exports metrics that measure information about
       individual containers and groups of containers, called pods.

       A brief description of the pmdapodman 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.

       -l   Location of the log file.  By default, a log file named
            podman.log is written in the current directory of pmcd(1) when
            pmdapodman 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.

INSTALLATION         top

       The podman PMDA is installed and available by default on Linux.  If
       you want to undo the installation, do the following as root:

            # cd $PCP_PMDAS_DIR/podman
            # ./Remove

       If you want to establish access to the names, help text and values
       for the podman performance metrics once more, after removal, do the
       following as root:

            # cd $PCP_PMDAS_DIR/podman
            # ./Install

       pmdapodman 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.

FILES         top

                 default help text file for the podman metrics
                 installation script for the pmdapodman agent
                 undo installation script for the pmdapodman agent
                 default log file for error messages and other information
                 from pmdapodman


       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).
