Activity Logs? Perfmon?

[Ziizzu]

Is there a program similar to Perfmon for the Mac. Or is there a way to generate logs via Activity Monitor? I need a log of system activity over a 2 hour period. The more activities that are tracked the better. Processor,Disk, Memory..etc. Thanks in advance.

Maybe 'sar'

You could try sar, though it won't give you the pretty graphs or the notifications.

I'm looking for something similar, but with notifications when something hits a certain threshold (without writing scripts for each).
