ntop would probably be the main "free" flow based monitor, though there are some really really nice commercial products.
I just need something that gives me a usage graph at daily, weekly, and monthly intervals with a 95% line.
It looks like ntop works with RRD so that seems like a good solution.
Thanks for your help!
