[jira] [Comment Edited] (MESOS-2961) Add cpuacct subsystem to cgroups

["Jojy Varghese (JIRA)" <ji...@apache.org>]

---------------------------------------------------------------

On further going through tests am realizing that the stats information can be retrieved using cgroup::stat function. Its a bit hidden. Wondering if we can create a cgroups subsystem within mesos with functionality isolated per subsystem ?
With a system view, we also achieve:
 - Modularity (reusable)
 - Add features like event notification which can then be broadcasted to listeners.

> Current cgroups implementation does not have a cpuacct subsystem implementation. This subsystem reports important metrics like user and system CPU ticks spent by a process.
