I've been running NBAR for about a year now without any issues. I have a
couple scripts to feed the Data into MRTG if anybody is interested.

Thanx, kj

I just turned on nbar(ip nbar protocol-discovery) on all my router
interfaces, I Im running a 2600 with 2Serial T1 interfaces and 1
FastEthernet interface, I currently graph cpu utilization, so I will let
it
run for a day and report back the cpu statistics.

This is the first time I've heard of NBAR, and it's been
around since 12.0(5)XE2! I sure feel out of the loop. ;)

This just sounds too cool. What is the router overhead? It's
got to be high if it's doing payload inspection. I want
to see a pre and post implementation router-cpu graph.
