      Given a running instance of Open vSwitch with flows being processed by either the kernel or userspace datapath (OVS-DPDK),

      When the system administrator issues a command to retrieve statistics on flow insertions and deletions,

      Then, OVS should return a report showing the number of flow insertions and deletions per second, for both kernel and userspace datapaths.
      If enabled, the report should include detailed statistics for offloaded flows distinguishing them from regular flows.

      It would be a good troubleshooting tool to get statistics related to flow insertion and delete rates.

      This should exist for both the kernel and userspace datapath, preferably something unified. In addition, it might also be nice to not only get this globally but also for offloaded flows.

      Maybe we can get some kind of histogram to get the various insertions/deletions per second. Like what currently exists for PMDs only:

       

      ovs-vsctl set Open_vSwitch . other_config:pmd-perf-metrics=true
ovs-appctl dpif-netdev/pmd-perf-show
