If you go into DMS service there is a tab for Event Subscription. if you register a topic, then you will get notification of every event that happens in the event tab. For example, then you reboot a DMS instance, there will be two events (replication application shutdown followed by replication application restarted.) if on the other hand, you use EventBridge, then you will only get a single event from CloudTrail called "RebootReplicationInstance". The same holds true with events surrounding tasks. We intentionally caused an issue with a task by deleting the source database. within the DMS application, we can see the following:
- Replication task has started
- Replication task has failed. Reason: Last Error ODBC general error. Stop Reason RECOVERABLE_ERROR Error Level RECOVERABLE.
But if you look at the events emitted by EventBridge, you only see the StartReplicationTask coming from CloudTrails. Sorry for the long question, but why does EventBridge not provide the same sequence of events that you can see within the Application.
