Performance Monitoring

Hi all

The place I work for is about to to place there database server under heavy load for testing and would like the effect recorded as much as possible.

Can anyone point me in the right direction with respect to real time system monitoring. I am aware of of 'sar', vmstat etc and hope to gather most data from it. However I was wondering if there are any other tools/methods by which I can capture this performance data in real time.

any help appreciated

thanks

Which OS? - for example, HPUX has glance which is very useful.
