Hi Pvpalval,
Please find my comments inline.
I can see 5 Processors under CPU in Introscope. What does that mean?
--> These are the hardware processors 5 core CPU Processor machine. And the values you are getting is the CPU Utilization (Aggregate %) on that individual processor by all system and java processes.
Also for eg. If the CPU Utilization goes high due to opening of a big file in Production environment, how and where can we drill down and show the exact reason for CPU of particular process going high?
-->To answer your question, it is not possible to drill down to know exactly which PID(Process) or System user is utilizing high CPU from Wily. You can only make out a difference using '% process' and '% aggregate' value, Where -
'% process' - indicates CPU Utilization by JVM process running on to that server which Wily agent is instrumented with. [And to my experience, if it goes beyond 9-10% value, there is some issue in the application]
'% aggregate' - indicates CPU Utilization by all processes (including system level) and that too per processor.
Actually if you ask me, this sometimes gets very confusing if you say to a developer\Prod management. That is the reason if I see some high '% process' value, I run $ Top command on my Linux boxes to know which particular PID is consuming high CPU.
Hope it helps.
