I have 4 Dell Poweredge 2850 with red hat 3. Opmanger is monitoring their CPU Utilization, but most of the time the current value is the same.
We used the command "top b n 1 | grep -i 'CPU*'". I notice if I used n=2 or 3, the second or third "command" shows up a real value. I attached the example.
Why does this happen? Are there any way to solve this?
I would like to add up USED CPu and System CPU. Are there any way to do this?
