PMDAPODMAN(1)            General Commands Manual           PMDAPODMAN(1)

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.

PCP ENVIRONMENT         top

       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).
