NMon from IBM and it's free (as a beer).It's originally written for
AIX but it is still one of the best tools I've ever seen. It can also
collect data in the background as a detached job and they also have a
nice "analyzer spreadsheet" if you want pretty graphics (I haven't
tested that on OpenOffice but might work). I mainly use that at work
for performance and machine analysis.
