SLE Performance Co-Pilot (pcp): Performance Co-Pilot

Description

Performance Co-Pilot (PCP) is a system performance analysis toolkit.

Usage

$ podman run -d \
    --name pcp \
    --systemd always \
    -p 44321:44321 \
    -p 44322:44322 \
    -v pcp-archives:/var/log/pcp/pmlogger \
    registry.suse.com/suse/pcp:6.2.0

Note: On SELinux enabled systems, the following boolean needs to be set: sudo setsebool -P container_manage_cgroup true

Enabling host processes, network and container metrics

$ sudo podman run -d \
    --name pcp \
    --privileged \
    --net host \
    --systemd always \
    -e HOST_MOUNT=/host \
    -v pcp-archives:/var/log/pcp/pmlogger \
    -v /:/host:ro,rslave \
    registry.suse.com/suse/pcp:6.2.0

Configuration

Environment variables

PCP_SERVICES

Default: pmcd,pmie,pmlogger,pmproxy

Comma-separated list of PCP services to start.

HOST_MOUNT

Default: unset.

Path inside the container to the bind mount of / on the host.

REDIS_SERVERS

Default: localhost:6379

Redis connection spec(s) - could be any individual cluster host, and all hosts in the cluster will be automatically discovered. Alternately, use comma-separated hostspecs (non-clustered setup)

Configuration files

For custom configuration options beyond the above environment variables, it is advised to use a bind mount with a configuration file on the host to the container. Example command to run a pmlogger-only container:

$ podman run -d \
    --name pmlogger \
    --systemd always \
    -e PCP_SERVICES=pmlogger \
    -v $(pwd)/pmlogger.control:/etc/pcp/pmlogger/control.d/local:z \
    -v pcp-archives:/var/log/pcp/pmlogger \
    registry.suse.com/suse/pcp:6.2.0

pmlogger.control:

$version=1.1

remote.pmcdhost.corp    n   n   PCP_ARCHIVE_DIR/remote_pmcd -N -r -T24h10m -c config.default -v 100Mb

Volumes

/var/log/pcp/pmlogger

Performance Co-Pilot archive files with historical metrics.

Ports

The pmcd daemon listens on this port and exposes the PMAPI(3) to access metrics.

44322/tcp

The pmproxy daemon listens on this port and exposes the REST PMWEBAPI(3) to access metrics.
