CentOS 6.3 Performance Issue on DL360e Gen8 Server

Ragie — Thu, 11 Apr 2013 01:11:14 GMT

Hi,

We have a very big problem about our server.

We managed to intall CentOS 6.3 on our DL3603 Gen8 Server with B320i Controller.

But the main problem is when we issue TOP command the server's CPU usage is too high.

This is not normal, right?

If you encounter this problem and found a resolution.

Please give us tips and advise how to fix this issue.

Many Thanks.

P.S. This thread has been moevd from ProLiant Servers (ML,DL,SL) to Linux > general - Hp Forums moderator

Please remember that people on this forum cannot see your screen.
Describing the exact values you think are "too high" or even posting a screenshot would be useful.

The "top" command was originally designed to list the processes according to their CPU usage, heaviest CPU users first (look at the %CPU column to confirm). Now look at the processes that tend to spend most of the time at the top of the "top" list. Are they your application processes, or something else?

If they are your application processes, then you probably should tell the name and version of your application and describe its workload. If they are something else, the next step is to identify them and see if they are performing some useful function or not. For example, there might be a web browser that has accidentally been left running when a remote session was cut off - that is probably not useful at all, and can be killed.
