Nowhere ;-) how about just return the counter values for the correct tap
device through API?

So it is basically:
1.) a wrapper from netX to correct tap
2.) query tap counter inout / output values
3.) allow to query this through API

So it is at least possible to implement traffic account in external
software. You jsut have to query the API every X seconds and detect
resets yourself. It acts than basically like SNMP traffic counters in
