I see a discrepancy between my system and the documentation at https://www.kernel.org/doc/Documentation/cgroups/cpuacct.txt Specifically, the references in the following paragraph to /sys/fs/cgroup appear to be incorrect on my system, and should instead be references to /sys/fs/cgroup/cpuacct Doc: New accounting groups can be created under the parent group /sys/fs/cgroup. # cd /sys/fs/cgroup # mkdir g1 # echo $$ > g1/tasks The above steps create a new group g1 and move the current shell process (bash) into it. CPU time consumed by this bash and its children can be obtained from g1/cpuacct.usage and the same is accumulated in /sys/fs/cgroup/cpuacct.usage also.
