Managing RabbitMQ Instance Tags

Tags facilitate RabbitMQ instance identification and management.

If your organization has configured tag policies for DMS for RabbitMQ, add tags to RabbitMQ instances based on the tag policies. If a tag does not comply with the tag policies, the tag fails to be added.

A tag consists of a tag key and a tag value. Table 1 lists the tag key and value requirements.
