I have three OS/390 v2.10 under z/VM. while i monitoring OS/390 Guest by perfomance toolkit, supervisor CPU usage is high around 20~30% and Emulated CPU is around 30~40%. I think supervisor CPU% is used by VM system(CP) and emulated CPU% used by Guest OS.
1)when or for what the supervisor CPU is used? 2)how can i find or trace what is the cause to use supervisor CPU?
