Why Can't I View the Monitoring Data of a RabbitMQ Instance?

RabbitMQ 3.x.x Instance

Monitoring data may fail to be displayed if the queue name or virtual host name of a RabbitMQ 3.x.x instance meets any of the following conditions:

  • The queue name starts with a special character, for example, a dot (.). You are advised to delete queues whose names contain special characters.
  • The virtual host name starts with a special character, for example, a dot (.). You are advised to delete virtual hosts whose names contain special characters The queue name of a RabbitMQ 3.x.x instance is displayed in two ways on the monitoring page. The name of a queue is displayed if the queue is on the default virtual host. If a queue is not on the default virtual host, the queue name is displayed in the format "Name of the virtual host where the queue is__Queue name". For example, if the test01 queue is on Vhost-13142708, the queue name displayed on the monitoring page is Vhost-13142708__test01.

When the queue or virtual host name of a RabbitMQ 3.x.x instance contains special characters, such as %, |, and /, the special characters are displayed as underscores (_) on the monitoring page. For example, the name of queue Queue.1%1|2_3/ in the default virtual host is displayed as Queue.1_1_2_3_ on the monitoring page.
