This Epic will track work to enable northd / RAFT metrics collection. This Epic will reuse the same OVS/OVN exporter that will be deployed on Dataplane nodes and for ovn-controller running on OCP nodes. The deployment strategy will be slightly different because OCP nodes run pods, not containers; and because northd and RAFT are not running as DaemonSets and have different requirements in terms of downtime. (E.g. northd is stateless and can be relatively safely restarted as needed.)
