OpenNMS for Bandwidth Monitoring and Interacting with Sonicwall

I'm working with OpenNMS for the first time, primarily for the purpose of bandwidth monitoring. But I do also want to get a decent network map drawn out with it as well.

I've gotten it up and running so far, and most devices on the network have been discovered without issue. However, I did want to see the network drawning out so that I could see what devices are connected to our switch (3com Baseline Switch 2916-SFP), along with getting bandwidth data from our Sonicwall TZ-200 so that I can figure out if a machine is using up too much bandwidth.

It feels like I've overlooked something with regards to SNMP or maybe on the Sonicwall itself (which should be discovered by OpenNMS by this time tomorrow since I just added it to the discovery).

Any advice, pitfalls to be aware of, or configs to pay attention to is greatly appreciated.

PS - I'm running OpenNMS on Ubuntu.

with a sonicwall (and most other snmp devices) you have to enable it. The public snmp will give you some basic stuff but the good stuff comes from "traps". So you add a trap address of the opennms setup to the sonicwall and choose what information gets sent. Warning: the bandwidth stuff can take up some decent lan bandwith.

Apologies for being late on this. I've been swamped, but this is a decent solution that appears it'll do this trick... thanks!
