It's not the only option, but probably the safest and
simplest for someone claiming to be a newbie.

I prefer to run several instances of MRTG, in daemon mode, 
under control of a launcher script in /etc/init.d/.  This 
won't necessarily suit all circumstances, but I find it 
useful because it allows adding or updating configurations 
for specific clusters of targets without either interrupting 
the rest of the monitoring or killing everything with a typo.

I've just checked one of our network-monitoring boxes, and
found 49 instances of MRTG covering over 5000 targets.
