Put up a sinkhole on your network and run feel free to run all types of analyzers on it, including but not limited to: snort, rrdtool, tcpdump, mrtg, et al.

If you have a fairly large sized network with multiple POPs, consider anycasting your sinkholes.

And... route all the bogons to sinkholes.. set next-hop to sinkhole anycast/unicast addr (whichever u use either anycast or unicast).
