I have a server which is idling below 5% cpu load most of the time, except from a few times a day where I can see some minor cpu spikes. I found out about this by using PRTG.
How can I find out what process is causing the cpu spikes? It's easy to monitor WMI CPU load with PRTG, but what I would also really need is a way to log the most CPU-Intensive processes in regular intervals.
I guess this can be done with perfmon, but which performance counters do I need for this job?
