No notification sent when status is updated from DOWN to ACTIVE when creating new port

[Alexey Weyl]

The problem is the following:
1. I am listening to all of the notification from neutron.
2. When I am creating a new nova instance, then I get notification about the port creation and update. I receive there only notification with status="DOWN". After a few seconds that I have received a notification of the status="DOWN", I've checked the ports status using the command line and see that its status is "ACTIVE", but no notification was sent about that on the oslo bus.

Can you please add notifications when the port status is changed?

We don't issue update event on transition to ACTIVE because it's guarded by provisioning blocks, and the status is updated via a custom endpoint. We may want to make the API layer to trigger the update event for that custom endpoint.

Vitrage as a user of neutron (and I guess other internal and external systems) needs to know about any status change of neutron port and network.
I think each system / project should provide via notification any status change of each one of its elements because the status of an element is the most important thing.
Right?
