Using snort for network stats?

[Michael Miller <michael.miller () state co us>]

Since I'm using snort to capture nearly everything that enters and exists
our network, I was curious to see if there was a utility to show network
metrics based on that data. Google didn't find much (or I asked the wrong
questions) and Ethereal is choking on the large dataset, so that's out. I'm
mostly interested in effective thruput, percentages of TCP/UDP/ICMP data,
breakdown of traffic by protocol, etc.
