Hi, We have a Stein deployment using Kolla Ansible 8.0.1 (the latest) and have enabled the deployment of the neutron metering agent. We have separate network nodes and compute nodes and use DVR. DVR is working properly, where ingress and egress traffic to floating IPs binded to fixed IPs flows directly to our upstream routers, not through the network nodes, whereas SNAT traffic flows through the network nodes. I configured the agent using the simplest of rules to test the agent (as cloud admin): openstack network meter create --description Shared --share bandwidth openstack network meter rule create --egress --remote-ip-prefix 0.0.0.0/0 bandwidth openstack network meter rule create --ingress --remote-ip-prefix 0.0.0.0/0 bandwidth None of the compute nodes appeared to be metering. So I checked the metering agent log (see below my signature for a snippet of the respective log entries), which shows that no routers are being found. Note that the Debug flag is set to True (in metering_agent.ini). On the primary network node, the "get_traffic_counters" method returns a list of all routers for every project, and runs a respective meter retrieval for each, such as the following, for each router: 2019-10-17 15:29:30.437 6 DEBUG neutron.agent.linux.utils [-] Running command (rootwrap daemon): ['ip', 'netns', 'exec', 'qrouter-e0d2ee4f-76ec-4043-93f7-a47fae488d59', 'iptables', '-t', 'filter', '-L', 'neutron-meter-l-fb2c912d-9ce', '-n', '-v', '-x', '-w', '10', '-Z'] execute_rootwrap_daemon /var/lib/kolla/venv/lib/python2.7/site-packages/neutron/agent/linux/util s.py:103 However, a single metering report is being created. Only one debug row appears in the log, and only one "bandwidth metric" measure is added to Gnocchi: 2019-10-17 15:38:15.494 6 DEBUG neutron.services.metering.agents.metering_agent [-] Send metering report: {'label_id': u'fb2c912d-9ced-433b-914e-df6526e034d1', 'time': 30, 'pkts': 0, 'tenant_id': u'96b2e5246a7744219e2af51f0e7b91d6', 'first_update': 1571300562, 'bytes': 0, 'host': 'networknode002', 'last_update': 1571344695} _metering_notification /var/lib/kolla/venv/lib/python2.7/site-packages/neutron/services/meterin g/agents/metering_agent.py:103 No errors are being reported in the logs. Am I missing something? Thanks!
