And then there's collectl - see: collectl

It can do most anything from simple interactive monitoring of a few 'subsystems' like cpu, disk, etc and/or writing the data to disk and letting you play it back later. For more advanced topics you can have it send its data to higher level monitoring tools like ganglia.

It even has a --vmstat switch which means you can play back old data in vmstat format with timestamps, just one of many options.

The key is collectl is very lightweight, using less than 0.5% CPU when sampling everything every 10 seconds. Most users simply enable it as a daemon and keep it running forever. Then if you have a problem, the data you need has probably already been collected for you.
