i need calculate traffic usage of my router and floating ip in ovn base openstack cluster.
as you know when you use floating ip or router you have logical port not ovs port. that means all nat and snat perform by flow tables. but im not sure how can i get exact amount of traffic used in these logic ports?

in flow entries you can see n_packets, n_bytes but i’m not sure that be the exact amount of traffic.
