Steps to deploy RabbitMQ cluster

N/A

Steps to reproduce the behavior in question

1. Enable the management console plugin. rabbitmq-plugins enable rabbitmq_management
2. Enable the MQTT plugin. rabbitmq-plugins enable rabbitmq_mqtt
3. Start subscribing to MQTT topics.
4. Start publishing MQTT messages on those topics.

Messages are being sent and received, but no statistics are being shown on the Overview page.

Also, when looking at the Queue, no information is available...

I believe this to be odd since I was uses to seeing information on these pages when using AMQP...

Thoughts?

There is a dedicated documentation section in the MQTT guide. Some metrics are AMQP 0-9-1 specific and with native MQTT starting with 3.12, MQTT connections no longer rely on AMQP 0-9-1 and thus those metrics are never emitted.

Use Prometheus and Grafana. They have been the recommended option for monitoring for years.

Thanks for the information. That was what I needed. I understand using Prometheus and Grafana for monitor, but it was always nice seeing the charts directly in RabbitMQ.
