I have many FAS 2552 HA pairs forming a cluster (1 HA pair = 1 cluster) and receive more and more "node resources over utilized" that I am trying to analyze.
I fired some "statics" commands and what I don't really understand is the difference between cpu avg and cpu busy.
What I think I understood is cpu avg is the avg utilization of all cpu .. but what about cpu busy ? In my case I see lots of differences between both counters, for instance I see regularly things like "cpu avg = 50%, cpu busy = 90 %. Could you please be very explicit and explain the cpu busy in simple words ?
Thank you in advance and please tell me if I missed some descriptions.
