public final class Cgroup
extends ProcFile

/proc/[pid]/cgroup (since Linux 2.6.24)

This file describes control groups to which the process/task belongs. For each cgroup hierarchy there is one entry containing colon-separated fields of the form:

5:cpuacct,cpu,cpuset:/daemons

The colon-separated fields are, from left to right:

1. hierarchy ID number
2. set of subsystems bound to the hierarchy
3. control group in the hierarchy to which the process belongs

This file is present only if the CONFIG_CGROUPS kernel configuration option is enabled.
