Thanks a lot! I'm trying to figure out how to set CGroup now - don't know it before.
One more question, I just find /proc/[PID]/stat also contains such information: processCPUTime = utime + stime + cutime + cstime I'm wondering whether there are any significant differences from reading /proc directly and the way Collectd used? Thank you!
