That would be a mess to try to implement in SNMP because of how variable it is. You would be well served by Netflow graphs. You can get traffic breakdowns in a very granular fashion and the right frontend will allow you to drill down in a very granular fashion. There are a couple of utils that can give you netflow capabilities, including flowd and pfflowd in the ports tree. You can also look into Ntop if you are interested in a pretty web frontend for it, or maybe the Argus project will have something for you. DS
