(PMDA)
Синопсис (Synopsis)
$PCP_PMDAS_DIR/podman/pmdapodman [-d domain] [-l logfile]
Описание (Description)
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.
Установка (Installation)
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.

Окружение PCP (PCP environment)
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).
