Here is the status update / focus setting mail about notification work
for week 26.

[Undecided] https://bugs.launchpad.net/nova/+bug/1684860 Versioned 
server notifications don't include updated_at
Takashi proposed the fix https://review.openstack.org/#/c/475276/ that 
only needs a second +2.

[Low] https://bugs.launchpad.net/nova/+bug/1696152 nova notifications
use nova-api as binary name instead of nova-osapi_compute
Agreed not to change the binary name in the notifications. Instead we
make an enum for that name to show that the name is intentional.
Patch has been proposed: https://review.openstack.org/#/c/476538/

[Undecided] https://bugs.launchpad.net/nova/+bug/1699115 api.fault 
notification is never emitted
It seems that the legacy api.fault notification is never emited from 
nova. More details and the question about the way forward is in a 
separate ML thread 

[Undecided] https://bugs.launchpad.net/nova/+bug/1698779 aggregate 
related notification samples are missing from the notification dev-ref
It is a doc generation bug. Fix and improvement on doc generation has 
been proposed https://review.openstack.org/#/c/475349/

[Undecide] https://bugs.launchpad.net/nova/+bug/1700496 Notifications 
are emitted per-cell instead of globally
Vitrage tempest test was broken due to missing notifications from 
nova-compute caused by the cells devstack change 
https://review.openstack.org/#/c/436094/. Revert is on the way 
https://review.openstack.org/#/c/477436/. The final solution is to 
configure a separate and non cell local transport_url for 
notifications. This is already possible with current oslo.messaging 

Versioned notification transformation
Patches needs only a second +2:
* https://review.openstack.org/#/c/402124/ Transform
instance.live_migration_rollback notification

Patches that looks good from the subteam perspective:

Searchlight integration
bp additional-notification-fields-for-searchlight
The next two patches in the series needs just a second +2. The last 
patch needs a rebase due to conflict

Small improvements
* https://review.openstack.org/#/c/428199/ Improve assertJsonEqual
error reporting

* https://review.openstack.org/#/q/topic:refactor-notification-samples
Factor out duplicated notification sample data
This is a start of a longer patch series to deduplicate notification
sample data. The third patch already shows how much sample data can be
deleted from nova tree. We added a minimal hand rolled json ref
implementation to notification sample test as the existing python json
ref implementations are not well maintained.

Weekly meeting
The notification subteam holds it's weekly meeting on Tuesday 17:00 UTC
on openstack-meeting-4. The next meeting will be held on 27th of June.
