Have a look at rrdtutorial (in a man/ directory near you), its' fairly 
well written.

I knocked together some simple scripts to monitor some appservers (disk,cpu,process
count etc) but they get unwieldy very quickly - just a few boxes and it started
to get out of hand.

If you're going to be doing any gathering/graphing for this kind of thing, have
a look at cricket (ports/net-mgmt/cricket) - it makes using RRD a breeze
(though I would still read the tutorial at least, it does help to have a rough
understanding of the backend).

Favours SNMP, but you can use any script you like easily enough
(I have a ruby-ldap based version that pulls stats directly from
openldap, and it took an hour to get it graphing).
