How should I approach a RabbitMQ upgrade?
An upgrade needs a compatibility check, a tested release and a recovery path. Which changes deserve particular attention before the new version reaches production?
What needs backing up or preserving in RabbitMQ?
Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
What should I check first when RabbitMQ fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
How should I handle configuration and secrets in RabbitMQ?
Configuration must be available to the application without exposing credentials in source control, logs or browser code. What belongs in the runtime and which access controls matter?

Measure publish rate, consumer throughput, acknowledgement latency and queue growth. Tune prefetch to balance parallel work with fair delivery and memory use. Large unbounded queues often indicate a processing bottleneck; adding consumers helps only when the work and downstream systems can scale.
