The best way is to install and use the System Activity Reporting (SAR)
system. It's native, available, as detailed or general as you want and
allows a lot of way to "slice" the results. Frequency of sampling is
also under your control to allow chasing those particularly nasty
"extraneous events" that might be frequent.
