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.
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
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
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.

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
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).
