My understanding of how this works is that the PIX actually keeps track of the traffic in and out of each interface (as well as a bunch of other stuff). All that we need to do with snmp is read the current value of the counter. So, once a day/week/month/whatever, we snmp set the counters on the OIDs interfaces.ifTable.ifEntry.ifInOctets.x (where x is the interface ID of the external interface) and interfaces.ifTable.ifEntry.ifOutOctets.x to zero, and at the end of the day/week/month/whatever, we read the value of the counter that the PIX has been incrementing as it passes traffic. If my understanding is correct, the PIX is doing most of the work here, we just have to read the correct counters and analyse the data as required.
