use a 7-tuple.
An aggregation could be something basic like this:
This would give you SNMP equivalent for byte accounting on interfaces
without requiring full flow accounting IF you're not forced to do sampling
and IF you have flexible netflow.
Another much more recent method around SNMP (sorry SNMP, I'm over you) is
streaming telemetry, which is part of Netconf/YANG/OpenConfig.
This is more of a push method for these yang data models(the relevent one
here being snmp interfaces table).
It already exists on some Juniper and Cisco platforms.
