Module: check_mk Branch: master Commit: 5d6f5ccc344469f003db866ca9b3f947b3bfb432 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=5d6f5ccc344469… Author: Óscar Nájera <on(a)mathias-kettner.de> Date: Mon Nov 26 15:34:02 2018 +0100 6653 Threshold Levels for steal cpu time in Linux/Unix Steal CPU time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. Its presense can be now monitored by setting up threshold limits as a fraction of the total CPU utilization time.
