RabbitMQ 3.9.9   
Erlang 23.3.4.8
Cluster name: xxx@yyy

The cluster name can be used by clients to identify clusters over AMQP connections, 
and is used by the shovel and federation plugins to identify which clusters a message has been routed through.

Note that the cluster name is announced to clients in the AMQP server properties; 
i.e. before authentication has taken place. Therefore it should not be considered secret.

The cluster name is generated by default from the name of the first node in the cluster, but can be changed.

Channels
同连接里的  Channels 信息 


Channel：通道名称。
User name：该通道登录使用的用户名。
Model：通道确认模式，C 表示 confirm；T 表示事务。
State：通道当前的状态，running 表示运行中；idle 表示空闲。
Unconfirmed：待确认的消息总数。
Prefetch：
Prefetch 表示每个消费者最大的能承受的未确认消息数目，
用来指定一个消费者一次可以从 RabbitMQ 中获取多少条消息并缓存在消费者中，
一旦消费者的缓冲区满了，RabbitMQ 将会停止投递新的消息到该消费者中直到它发出有消息被 ack 了。
消费者负责不断处理消息，不断 ack，然后只要 unAcked 数少于 prefetch * consumer 数目，RabbitMQ 就不断将消息投递过去。

Unacker：待 ack 的消息总数
publish：消息生产者发送消息的速率
confirm：消息生产者确认消息的速率
unroutable (drop)：表示未被接收，且已经删除了的消息
deliver/get：消息消费者获取消息的速率
ack：消息消费者 ack 消息的速率

This guide covers RabbitMQ monitoring with two popular tools: 
Prometheus, a monitoring toolkit; and Grafana, a metrics visualisation system.

These tools together form a powerful toolkit for long-term metric collection and monitoring of RabbitMQ clusters. 
While RabbitMQ management UI also provides access to a subset of metrics, 
it by design doesn't try to be a long term metric collection solution.


RabbitMQ ships with built-in Prometheus & Grafana support.

Support for Prometheus metric collector ships in the rabbitmq_prometheus plugin. 
The plugin exposes all RabbitMQ metrics on a dedicated TCP port, in Prometheus text format.
