IMHO,
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.
