Hello James: In ML2/OVN you can use the ML2/OVN Network Logging ( https://docs.openstack.org/neutron/latest/contributor/internals/ovn/ovn_netw...). Right now it works for security groups. That will create a meter register that monitors the traffic of a OVN Port Group (a SG in Neutron terms). Maybe it could be possible to propose an extension to this feature to monitor single ports. It could be a feasible RFE. Regards. On Fri, Aug 29, 2025 at 1:20 AM Karl Kloppenborg < kkloppenborg@resetdata.com.au> wrote:
Not that this helps too much but we resulted to writing an agent that pulls the information directly from openvswitch etc. We then combined that with Netflow from our PE routing edge.

You don't often get email from james.denton@rackspace.com. Learn why this is important <https://aka.ms/LearnAboutSenderIdentification> Hello all,
Is anyone aware of a method to gather statistics (bytes in/out, packets, etc.) for logical router ports or similar when using ML2/OVN? I understand neutron-metering-agent parity is currently a feature gap, but I’m curious if there’s some OVN-native functionality that can provide those details. The ask is to provide a bytes-in/out counter for tenant routers, specifically on the external interface(s).
Thanks, James
