High CPU load average; how to find the root cause?












1















It is hard task to find the root cause of CPU load average
many commands are used to give partial picture.



I am not sure if somewhere we can find a tool that knows how many CPU's we have on machine and verify the load average and give results if load average is more then normal.



And if load average is high, then find the root cause.



What I have already find:



on machine we find the following ( actually not )




  1. no network problem


  2. no disks problem


  3. log as messages is clean without errors



Any tips about, how to find the root cause of high CPU load average?
