Sent a patch upstream for DPDK, http://mails.dpdk.org/archives/dev/2019-August/141710.html as unfortunately this can not be done from the OVS side only. Once this patch gets approved I can propose a patch for the OVS dpdk-next branch, once it has moved to 2.12 (due to some dependencies in the statistics). Sent out a v2 patch for OVS: https://mail.openvswitch.org/pipermail/ovs-dev/2019-October/363883.html Waiting for dpdk-latest rebase before I can send out an updated v3. dpdk-latest branch got updated, sent out a v3: https://mail.openvswitch.org/pipermail/ovs-dev/2019-November/365122.html Sent path after rebasing it to master with DPDK 19.11 https://mail.openvswitch.org/pipermail/ovs-dev/2019-December/365924.html Patch backported to OVs 2.12 and 2.13 FDN.

Please review the log below. Thanks! Jean [root@netqe7 jhsiao]# ovs-appctl coverage/read-counter vhost_notification "coverage/read-counter" is not a valid command (use "list-commands" to see a list of valid commands) ovs-appctl: ovs-vswitchd: server returned an error [root@netqe7 jhsiao]# rpm -q openvswitch2.11 openvswitch2.11-2.11.0-47.el7fdp.x86_64 [root@netqe7 jhsiao]# uname -r 3.10.0-1062.el7.x86_64 [root@netqe7 jhsiao]# Hi Jean, the "ovs-appctl coverage/read-counter" command is not supported in 2.11. You need to use the ovs-appctl coverage/show command, however, be warned that the value will only be displayed if the event has happened. The RFE has been verified: root@netqe7 ~]# ovs-appctl coverage/show | grep -i vhost vhost_notification 0.0/sec 0.000/sec 0.0000/sec total: 18481824 [root@netqe7 ~]# rpm -q openvswitch2.11 openvswitch2.11-2.11.0-47.el7fdp.x86_64 [root@netqe7 ~]# uname -r 3.10.0-1062.el7.x86_64 [root@netqe7 ~]# Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
