cgroups-exporter 0.7.0

prometheus exporter for cgroups v1

CGroups exporter

Exporter for CGroups metrics, for LXD/Docker/systemd.

Collects metrics for all cgroups based containers or SystemD services on the host machine, without the need to install separate exporters inside each container.

Installation

pip install cgroups-exporter

Example

A simple example collects all available metrics for LXD containers.

cgroups-exporter --cgroups-path "/sys/fs/cgroup/*/lxc.payload.*"

You can pass several path templates, then metrics will be collected from everyone.

In the example below, metrics will be collected for:

• All LXD containers
• All SystemD services running inside the LXD containers
• All Docker containers inside the LXD containers.
• All user slices (when used entering through the ssh the SystemD creates the slice named by template user-$UID)

cgroups-exporter \
  --cgroups-path \
      "/sys/fs/cgroup/*/lxc.payload.*/" \
      "/sys/fs/cgroup/unified/lxc.payload.*/**/*.service" \
      "/sys/fs/cgroup/unified/lxc.payload.*/**/user-*" \
      "/sys/fs/cgroup/cpu/lxc.payload.*/**/*.service" \
      "/sys/fs/cgroup/unified/**/user.slice/user-*" \
      "/sys/fs/cgroup/*/lxc.payload.*/docker/*"

Usage

Args that start with -- (eg. -s) can also be set in a config file (~/.cgroups-exporter.conf or /etc/cgroups-exporter.conf).

Config file syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax here).

If an arg is specified in more than one place, then commandline values override environment variables which override config file values which override defaults.

Environment variable CGROUPS_EXPORTER_CONFIG overwrites config file location.
