Can anyone offer up ideas on how you manage any automation in this regard for their infrastructure gear traffic graphs? (Commercial options welcome, off-list, but we're as small as our budget is).
Unless something else is out there that I've missed, I'm seriously considering writing up a module in Perl to put up on the CPAN that can scan my RANCID logs (and perhaps the devices directly for someone who doesn't use RANCID), send an aggregate 'are these changes authorized' email to an engineer, and then proceed to execute the proper commands within the proper MRTG directories if the engineer approves.
I use a mix of Cisco/FreeBSD&Quagga for routers, and Cisco/HP for switches, so it is not as simple as throwing a single command at all configs.
OpenNMS works great, but has a steeper learning curve than MRTG. It supports auto discovery of devices, and can pull interface statistics for all new devices/interfaces automatically. I'm graphing all interfaces on around 4 dozen Cisco switches and routers and various other devices on one fairly beefy Linux box. It also has a RANCID integration module, which I haven't had a chance to play with yet.

Actually it is that simple. As long as the device supports the IF-MIB SNMP table, then your SNMP system should have little problem discovering all interfaces. All devices you list above should work, assuming you've got net-snmp running on the freebsd box. -- Dan White
