Check out the sysstat project[0].
Useful utilities for what you're doing are sar, iostat, and pidstat.
Setting up a simple monitoring script using pidstat run out of cron
would be your best bet.
Pidstat can give you info on memory utilisation (paging, swapping,
rss), io, cpu utilisation, and context switches,
Interpreting the results is the trickier problem. :-)
