12 podman(1) is a utility for managing pods, containers and container
13 images, following the container pod concept popularized by Kubernetes.
14 pmdapodman is a Performance Metrics Domain Agent (PMDA) which extracts
15 performance metrics describing the state of containers and pods managed
16 by podman.
17
18 The podman PMDA exports metrics that measure information about individ‐
19 ual containers and groups of containers, called pods.
20
21 A brief description of the pmdapodman command line options follows:
22
23 -d It is absolutely crucial that the performance metrics domain num‐
24 ber specified here is unique and consistent. That is, domain
25 should be different for every PMDA on the one host, and the same
26 domain number should be used for the same PMDA on all hosts.
27
28 -l Location of the log file. By default, a log file named podman.log
29 is written in the current directory of pmcd(1) when pmdapodman is
30 started, i.e. $PCP_LOG_DIR/pmcd. If the log file cannot be cre‐
31 ated or is not writable, output is written to the standard error
32 instead.
33
35 The podman PMDA is installed and available by default on Linux. If you
36 want to undo the installation, do the following as root:
37
38 # cd $PCP_PMDAS_DIR/podman
39 # ./Remove
40
41 If you want to establish access to the names, help text and values for
42 the podman performance metrics once more, after removal, do the follow‐
43 ing as root:
44
45 # cd $PCP_PMDAS_DIR/podman
46 # ./Install
47
48 pmdapodman is launched by pmcd(1) and should never be executed
49 directly. The Install and Remove scripts notify pmcd(1) when the agent
50 is installed or removed.

66 Environment variables with the prefix PCP_ are used to parameterize the
67 file and directory names used by PCP. On each installation, the file
68 /etc/pcp.conf contains the local values for these variables. The
69 $PCP_CONF variable may be used to specify an alternative configuration
70 file, as described in pcp.conf(5).
