Enabling RabbitMQ Plug-ins

After creating a RabbitMQ instance, you can enable add-ons through plug-ins. The plug-ins are disabled by default when the instance is created.

RabbitMQ plug-ins can be used for testing and service migration. Do not use them for production. Reliability issues caused from using plug-ins are not within commitments on SLAs. For details, see Service Overview > Notes and Constraints.

Table 1 lists plug-ins supported by RabbitMQ. The ports of the plug-ins cannot be changed.

**Table 1** Plug-ins

Notes and Constraints

When plug-ins are enabled, the instance will not be restarted. However, enabling plug-ins rabbitmq_mqtt, rabbitmq_web_mqtt, rabbitmq_stomp, and rabbitmq_web_stomp will restart Keepalived and disconnect the instance. After the instance is disconnected, it may be automatically reconnected depending on the service logic.

The rabbitmq_shovel, rabbitmq_federation, and rabbitmq_tracing plug-ins can be enabled only for specific instances. For details, see Table 2.
