CPU utilization for a process in showing more than 100%
Hi All,
There is one RHEL 5 server in our . The server is running on VMware and having 5 CPUs. we have HPOV monitoring tool for monitoring the server. Have found that Java process on this server somtime is using more than 100% such as 350%, 460%. How it is possible. How a process can use more than 100%.
Can some one please clarify this.

Re: CPU utilization for a process in showing more than 100%
If you have multiple threads and each runs on a separate CPU, then you can have multiples of 100%.

Re: CPU utilization for a process in showing more than 100%
Thanks a lot for your information.
I have come across one more scenario where if just count the percentage of all the process it would show more than 100% on the the server where one CPU available. Is it possible?

Of course. The max should be N * 100%, where N is the number of CPUs.
