I am using an HP-UX 10.20 system. I have both a CPU & Memory question.
What is the difference between process CPU usage (%CPU per process) and the
“USER” CPU state?
From what I have been able to find and read online these two percentages are computed different ways. However most people I talk to make the assumption that the sum of the CPU state should approximate the sum of individual process CPU usage.
Should there be a correlation between the sum of the process CPU usage and the USER/SYSTEM CPU states? Below is an example.
Why is the amount of free memory greater than the real memory?
Thank you in advance.
