One Line Summary

Extending CPU accounting stats

Abstract

Currently the CPUacct cgroup controller only accounts for the system time and the user time. We propose to expand the accounting to provide stats such as number of running, sleeping and blocked tasks, time spent idling and/or waiting for I/O and so on. Such stats are available system-wide and are also needed for containers.
