Well, I've dug up a bunch of utilities I've found googling around for
such things. Over all, I'm very impressed with the amount of data
one can get from sar, iostat, mpstat, etc.
SGI has open sourced their Performance Co-Pilot (aka PCP :)
which looks like a really cool tool, just overly complicated for what
I've been asked to look at (and, I have a sneaking suspicion, would
actually introduce extraneous load to the systems being monitored).
Most people seem disappointed when they find out there aren't any
really cool GUI apps for this akin to NT's widget. Fortunately,
that's not at all what I'm looking for :) I want text-based output
I can parse with perl and dump into gnuplot in a very automated
fashion :)

It may look like I'm just sitting here doing nothing,
but I'm really actively waiting for all my problems to go away.
If you're not having fun, you're not doing it right!
