I've been all over this, trying out everything I could get my hands on.
 The biggest help has been that a few of them come as virtual
appliances.  Check out vmware.com and look at their selection of appliances.

I have had a ton of success with freeware called The Dude.  It's
primarily Win but they claim it runs on linux (haven't tried but it
probably will).

http://www.mikrotik.com/thedude.php

This program is heads above many commercial packages costing $$$.  It
will discover, map, graph, snmp, ping, alert, and make pancakes.  I have
it watching my network for up/down status and it calls me when
something's down.

MRTG is great for producing graphs of results (snmp helpful).  There's
another one by the same author (PRTG?) that does a bit more.

Good luck and let us know what works and doesn't.
