2.11. Obtaining Information About Control Groups

There are several ways to find and monitor control groups, subsystems, and hierarchies configured on your system.

2.11.1. Finding a Process

To find the cgroup to which a process belongs, run:
~]$ ps -O cgroup
Or, if you know the PID for the process, run:
~]$ cat /proc/PID/cgroup
where PID stands for a PID of the inspected process.
