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.

**Table 1** Tag key and value requirements
Name	Rules
Tag key	Cannot be left blank. Must be unique for the same instance. Can contain 1 to 128 characters. Can contain letters, digits, spaces, and special characters _.:=+-@ Cannot start or end with a space. Cannot start with _sys_.
Tag value	Can contain 0 to 255 characters. Can contain letters, digits, spaces, and special characters _.:=+-@ Cannot start or end with a space in instance creation.

Notes and Constraints
