The cgroup_exporter produces metrics from cgroups.
This exporter by default listens on port 9306 and all metrics are exposed via the /metrics endpoint.
The --config.paths flag is required and must point to paths of cgroups to monitor. If there is /sys/fs/cgroup/cpuacct/user.slice then the value for --config.paths would be /user.slice.
Example of running the Docker container
docker run -d -p 9306:9306 -v "/:/host:ro,rslave" treydock/cgroup_exporter --path.cgroup.root=/host/sys/fs/cgroup
Download the latest release
To produce the cgroup_exporter binaries:
make build
Or
go get github.com/treydock/cgroup_exporter
If you wish to collect process information for a cgroup pass the --collect.proc flag. If this exporter is not running as root then it's required to set capabilities to ensure the user running this exporter can read everything under procfs:
setcap cap_sys_ptrace=eip /usr/bin/cgroup_exporter
