The vhost library now provides finegrained statistics for guest
notifications:
- notifications for buffer reclaim by the guest,
- notifications for buffer availability to the guest,
Example before this patch:
$ ovs-appctl coverage/show |
grep vhost_notification
vhost_notification 0.0/sec 0.000/sec 2.0283/sec total: 7302
$ ovs-vsctl get interface vhost4 statistics |
sed -e 's#[{}]##g' -e 's#, #\n#g' |
grep guest_notifications
rx_q0_guest_notifications=66
tx_q0_guest_notifications=7236
