I'm looking for a program that will log system activity and be able to
report on historical data. For example:

Maximum nuber of precesses observed and when
Maximum usage of swap space observed and when
Maximum number of open files observed and when
...pagefaults...disk i/o...interrupts.... and so on...

I'd also like to see statistics on when is the busiest time of day,
busiest time of the week and so on...

Being able to look up a snapshot of the system at any given time would
also be nice. Say that on a given time there was a lot of disk i/o going
on, what else was happening at the same time?

Does such a tool exist?

Gunnar
