The above programs do not seem to give accurate details as to how much traffic has past through the monitored eth.
Hopefully one of you out there is currently using a open source program that is returning accurate values.
Im all ears if you are:)..
The typical solution for larger sites/ISPs is to generate NetFlow records,
either from the router (Cisco, Juniper, Procket, etc) or from ntop.
Use flow-tools, cflowd, NetFlowMet, etc to collect these.
There's a world of open source and commercial billing systems that
integrate with NetFlow, choose the one that best reflects your
needs. For a big but not exhaustive list see
This sort of approach scales to about 1Gbps. Which is OK, as incoming-byte
accounting at gigabit rates doesn't make too much sense anyway.
The nice thing about this approach is that you can hang ntop
off a switch's monitoring port or off a passive optical tap,
so none of the accounting system needs to be in publically
