Traffic analysis

I would like to monitor traffic by IP to find out who the hog on the network is but I haven’t been able to find a way yet. Can someone give me instructions?

Err, did you spend ANY time researching before posting by any chance?

netflow,
ip accounting,
ip firewall,

That’s three, of many, many, many ways.

Err, yes, I did, and if you can’t contribute anything positive to a thread, don’t bother - that’s exactly what the forums are here for. There are many ways to do many things; what I want is to see what people have found works best for them, as well as any tricks that make it easier.
