I also use MRTG, although my implementation uses RRDTool as the backend.
I then wrote a shell script  plugin for Nagios to check the RRD files
and notify on bandwidth spikes. I haven't contributed this yet, as I
have not had time to clean it up and make it more efficient. If
interested, let me know and I'll post it.
