or sent to syslog. These log messages provide a lot of information on events taking place in the RabbitMQ cluster. For example, a log message is generated whenever a new message is received in a queue, when that
To configure RabbitMQ, users need to make changes to therabbitmq.conffile. However, when deploying RabbitMQ on Kubernetes, the file is located within the running pods and should not be edited directly. Instead, configure RabbitMQ using Kubernetes resources, such as: ConfigMaps. Create a ConfigM...

Another reason to use a solution like Prometheus is that when you push RabbitMQ to its limit, the management UI can become sluggish or unresponsive. The UI is trying to operate on a machine that might already be close to 100% CPU utilisation. ...
Short queues are fastest; when a queue is empty, and it has consumers ready to receive messages, as soon as a message is received by the queue it goes straight out to the consumer. Having many messages in a queue places a heavy load on RAM usage. When this happens, RabbitMQ will star...
RabbitMQ tries to make things simple by allowing any client to connect to any node in a cluster. If a consumer connects to broker 1 but the queue exists on broker 2, then the traffic will be proxied from broker 2 to broker 1 and back. The consumer has no clue that the queue is hos...
