Maxim Khutornenko commented on AURORA-1220:
-------------------------------------------
In addition to the above, it would be great to track a
{{median_instance_update_time}} metric. This would be the time between
INSTANCE_UPDATING and INSTANCE_UPDATED instance events and would help job
owners track their instance downtime during updates.
> Add SLA stats tracking job updates

> With the scheduler updater graduating from beta, we should add job update
> metrics to help job owners track update history/performance, e.g.:
> *Per Job and Per cluster:*
> - updates_created
> - updates_succeeded
> - updates_failed
> - updates_aborted
> - updates_rolled_back
> - time_spent_in_active
> - instances_added
> - instances_removed
