Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

On one of our servers I used Perfmon to log CPU usage. It showed me several spikeat 100% but don't know what process(s) caused that. So, how can I log CPU usage for process which used more than 40%?

Thanks.

With Perfmon, use the "Process" counter container. You can then examine individual processes. To dig deeper use SysInternals (now MS) ProcessExplorer.

If you monitor your servers with SNMP, and store the recordings in something like Solarwinds Orion or MRTG or several other systems, you can keep a graph of CPU usage by process. You'll have to be able to keep the data by process name; I don't know if MRTG will do that OOTB or at all. I know that Orion will track named processes.

How about the "tasklist" command? it's actually really useful, try it with the '/v' option.

Oh and HERE's a guide to it.

Hope it helps.

You can also deploy nagios for monitoring
