I use nfcapd (part of nfdump) to capture the data, and have been using a
few of my own scripts to process the data. Not doing anything fancy
right now, just extracting data by IP address so I can graph user usage.

I'd like recommendations on Netflow collectors and analyzers. I played
briefly with nTop, the package Mikrotik sorta-recommends, but it was
just too unstable for my taste. (The nTop daemon died about four times
over the weekend.)
There's plenty of commercial Netflow tools out there, some of which run
for many thousands of dollars. Of course, I don't have THAT kind of
money, but there are a few less expensive packages as well. What works,
and what doesn't?
