personally, i prefer munin for this kind of job. i started out on cacti, 
which i favoured because it uses snmp, but when trying to get it to graph 
more than just the basic stuff its complexity just was too much.
they do have a ton of plugins out there - but many of them seem to be 
really hackish and difficult to get to work

with munin you can be up and running  within minutes (on gentoo and debian 
at least) and get so much more info out... and they too have a growing 
number of plugins available.

kind regards
