Pinned topic 100 % CPU Utilization-need to find root cause

‏2013-10-04T12:22:59Z |

Hi Folks,

We are getting high CPU utilization on Websphere application.

Please find the attached file and let us know ur opinion.

    Hi Pravin,

    Have you tried to use APD Lite to diagnose this?   If you look at the video on the main APD Lite page, you will see a root cause analysis based on application response time - however, all the charts in Eclipse can be toggled to show CPU time instead.  So you can drill down to the method with the CPU  problem .
