Question

Sudden High LINUX CPU Utilization...

Asked by: cjb123

Hello:

Starting the other day, we saw a CPU utilization on our production LINUX server go from a "normal" 10% average utilization to approx 45 - 60% utilization. It's been "pegged" at about
45 - 60% utilization since then.

When I do a "top" command, I get these results below.  Can you help me decipher these data?
If "top" is not the best command to use, please advise which command I should run and I'll provide supplement data in a follow-up post.  Thank you.

top - 16:43:43 up 75 days, 13:21, 36 users,  load average: 2.31, 2.36, 2.33
