How do you trace problem traffic?

How powerful of a box would a proxy need to be? Could I create such a thing efficiently from old server or workstation? I imagine that depends on the traffic.
I used to run a proxy and sniffer for ~100 users over a P4 512MB machine.
Don't need much.
Good deal, because that is about the exact specs of the spare hardware I have to use!

Need a better machine? I have that box sitting on my shelf, a Compaq with three NICs, 2GB of RAM, and decent sized hard drive. Get it for ya cheap, even load ntop for ya.

@PSX_Defector I appreciate the generous offer and I will let you know if I do. But this is a backseat project for me at best. Might try the port mirroring first but all this has to be done in my non-existent free time. I am sure you know how that goes.
Thanks.

A Proxy needs more power than a router but not much. It does very little work. I bet a PIII 600 would do the trick.

Is this crossing a firewall? If so, it should be able to tell you which devices are the nosiest.

@alexntg Yep, my branches use Juniper SSG-5's but I haven't seen any logging to do what you speak of.

What logging options does it have?
-
Very limited, only logs on the policy level for short increments (up to an hour) and looking across the Juniper boards it looks like everyone states to get good traffic logs you need to do port mirroring.

That's unfortunate.
