Working with Amazon EventBridge events and notifications in AWS Database Migration Service

You can use Amazon EventBridge to provide notification of when an AWS DMS event occurs, for example the creation or deletion of a replication instance. EventBridge receives events and routes notification of an event as defined by event rules. You can work with notifications in any form supported by Amazon EventBridge for an AWS Region. For more information about using Amazon EventBridge, see What is Amazon EventBridge? in the Amazon EventBridge User Guide.

Note

Working with Amazon EventBridge events is supported in AWS DMS version 3.4.5 and higher.

EventBridge receives an event, an indicator of a change in AWS DMS environment, and applies a rule to route the event to a notification mechanism. Rules match events to notification mechanisms based on the structure of the event, called an event pattern.

AWS DMS groups events into categories that you can apply an event rule to, so you can be notified when an event in that category occurs. For example, suppose that you apply an EventBridge event rule to the Creation category for a given replication instance. You're then notified whenever a creation-related event occurs that affects your replication instance. If you apply a rule to a Configuration Change category for a replication instance, you're notified when the replication instance's configuration is changed. For a list of the event categories provided by AWS DMS, see the AWS DMS event categories and event messages, following.

Note

To allow publishing from events.amazonaws.com, make sure to update your Amazon SNS topics' access policies. For more information, see Using resource-based policies for Amazon EventBridge in the Amazon EventBridge User Guide.

For more information about moving event subscriptions to Amazon EventBridge, see migrate active event subscriptions from DMS to Amazon EventBridge.

Using Amazon EventBridge event rules for AWS DMS

Amazon EventBridge sends event notifications to the addresses that you provide when you create an EventBridge event rule. You might want to create several different rules. For example, you might create one rule receiving all event notifications and another rule that includes only critical events for your production DMS resources. You can also turn on or turn off event notifications in EventBridge.

To create Amazon EventBridge rules that react to AWS DMS events

• Perform the steps described in Creating Amazon EventBridge rules that react to events in the Amazon EventBridge User Guide, and create a rule for AWS DMS events:

  1. Specify a notification action to take when EventBridge receives an event that matches the event pattern in the rule. When an event matches, EventBridge sends the event and invokes the action defined in the rule.

  2. For Service provider, choose AWS.

  3. For Service name, choose Database Migration Service (DMS).

You can then begin to receive event notifications.

The following JSON example shows an EventBridge events model for an AWS DMS service.

AWS DMS event categories and event messages

AWS DMS generates a significant number of events in categories that you can identify. Each category applies to a replication instance or replication task source types.

ReplicationInstance event messages

The following table shows the possible categories and events for the ReplicationInstance source type.

Category	Event ID	Description
Creation	DMS-EVENT-0067	A replication instance is being created.
Deletion	DMS-EVENT-0066	The replication instance is being deleted.
Configuration Change	DMS-EVENT-0012	The replication instance class for this replication instance is being changed.
Configuration Change	DMS-EVENT-0018	The storage for the replication instance is being increased.
Configuration Change	DMS-EVENT-0024	The replication instance is transitioning to a Multi-AZ configuration.
Configuration Change	DMS-EVENT-0030	The replication instance is transitioning to a Single-AZ configuration.
Maintenance	DMS-EVENT-0026	Offline maintenance of the replication instance is taking place. The replication instance is currently unavailable.
Creation	DMS-EVENT-0005	A replication instance has been created.
Deletion	DMS-EVENT-0003	The replication instance has been deleted.
Configuration Change	DMS-EVENT-0014	The replication instance class for this replication instance has changed.
Configuration Change	DMS-EVENT-0017	The storage for the replication instance has been increased.
Configuration Change	DMS-EVENT-0025	The replication instance has finished transitioning to a Multi-AZ configuration.
Configuration Change	DMS-EVENT-0029	The replication instance has finished transitioning to a Single-AZ configuration.
Maintenance	DMS-EVENT-0047	Management software on the replication instance has been updated.
Maintenance	DMS-EVENT-0027	Offline maintenance of the replication instance is complete. The replication instance is now available.
Maintenance	DMS-EVENT-0068	Replication instance is in a state that cannot be upgraded.
Failover	DMS-EVENT-0034	If you request Failover too frequently, this event occurs instead of regular failover events.
Failure	DMS-EVENT-0031	Replication instance put into %s state.
