MRTG is a wonderful little tool but I've seen a "slightly" misconfigured
cfg file (read overzealous) completely murder a non slouch of a server
in the past! So be wary of how much you're recording if you use that.
RRDtool might be a better option especially if you're trying to cut
down the resources actually used by the monitoring process, in that
it won't actually update the the images of the graphs until whatever
frontend you're using to view the results is called.
There's a rather cute little module called sysstats
(http://sourceforge.net/projects/webminstats) avaliable for webmin which
uses rrdtool to gather it's data. try using some of the scripts there
as a starting point. potentially you could even use a webserver on a
seperate system & nfs to update the graphs as a means of taking load
away from the box(en) your monitoring, though be wary as this could
be a double edged sword.
