Description Dan Williams 2020-03-17 02:52:43 UTC 
Setting monitor-all=true in each node's ovsdb causes each ovn-controller to monitor all chassis events, which reduces load on the southbound database at the expense of a bit more CPU and network activity on each node. This increases the ability to scale.

See OVN bug https://bugzilla.redhat.com/1808125 for more details.

Actually, this was for 4.3 and it was decided not to do the rebase for 4.3.
