history logs of high cpu utilization


Hi,
just want to ask if is there any way I can see the top percentage running process way back 5 hours ago or more?

I can only see the offending process on real time via top command .

Not unless you have a collector with history - try installing collectl.

you need to monitor your system and you can check the logs (see for example top -b). But without monitoring that information is not stored.

Unlike regular SAR Atop stores detailed process information that allows you to step back and forward through time. Like the others said though any such SAR needs to be installed beforehand.
