AWS Database Migration Service
API Reference (API Version 2016-01-01)


Creates an AWS DMS event notification subscription.

You can specify the type of source (SourceType) you want to be notified of, provide a list of AWS DMS source IDs (SourceIds) that triggers the events, and provide a list of event categories (EventCategories) for events you want to be notified of. If you specify both the SourceType and SourceIds, such as SourceType = replication-instance and SourceIdentifier = my-replinstance, you will be notified of all the replication instance events for the specified source. If you specify a SourceType but don't specify a SourceIdentifier, you receive notice of the events for that source type for all your AWS DMS sources. If you don't specify either SourceType nor SourceIdentifier, you will be notified of events generated from all AWS DMS sources belonging to your customer account.

For more information about AWS DMS events, see Working with Events and Notifications in the AWS Database MIgration Service User Guide.
