Hello Experts,

 We have a windows server 2003 server which is having issues with CPU Spike. The CPU spike happening randomly on the server for 20-30 mins and performance is will be normal post that.

Now my question is ,

 How to find out the perticular process which is causing the issue (Since it is happening randomly) ?

If I find that process , then I can use ProcDump to monitor it and create the dump file to analyse what thread is causing the CPU Spike.

Thanks,

-Prashant Girennavar.

I would not mind in using the Process Explorer tool at first before dumping the process and then wasting time in analyzing the dump. You can also check the thread stack using this tool.

Just sort it out from the CPU tab and see which process is spiking. First, you would have checked using the Task manager to see application is it but in that you cannot see the thread stack to see which DLL is loading and context switching the CPU.

Download the Process Explorer with this link

Awaiting your reply..!!

Good Luck..!!

Try the perfwiz tool and add the thread counters in it. According to the problem apply the change in the date and time in the tool run the wizard.

From this location you can download the tool and configure that on the machine.
