Default Network analyzer/monitor suggestion?

I'm looking for suggestions on a network monitoring/analyzing app I can put on a FreeBSD box in my environment.

I have Cisco switches, but unfortunately without NetFlow capabilities, otherwise I would likely use that.

What I CAN do is mirror traffic on my core switches to a port, and stick a FreeBSD box with a promiscuous NIC on that port. (It's called SPAN, as you Cisco techies already know, I'm sure.)

So, what I'd like is an app to capture that traffic, analyze, and report on it - I'm curious about things like protocols in use, bandwidth utilization, etc.

I know apps like tcpdump and Wireshark can capture this kind of traffic and allow me to look at it, but I'm really interested in bandwidth analysis, and if possible pretty graphs/charts that I could show non-techie people in the organization (like my boss, for instance). I'd be willing to settle for something I could export to an easily-readable csv or similar.

Any suggestions? Thanks!
