Please open a support ticket in such cases:
There are so many reasons for a high CPU. Without knowing the applications and system configuration in details it's hard to find the cause. I'd recommend switching the OneAgent into infrastructure mode at first, restart all processes and verify if the issue still persists.
Hi @Vibhash M.
First check the answer on the overhead of OneAgent in this thread to get familiar with the components of OA.
Having write that, there should be 4 dynatrace processes on your host.
Which one of them is causing the CPU overload?
