This assumes you have created a RabbitMQ user with the administrator tag.

Refer to the RabbitMQ REST API documentation.

The curl command with the --user option can be used to make an API connection to RabbitMQ. In this example, John Doe will make a connection to the RabbitMQ server listening on port 15671 and then list the nodes in the cluster.

curl
--request GET
--user john.doe:itsasecret
--url http://hostname:15671/api/nodes

Or, the details of a single node can be returned.

curl
--request GET
--user john.doe:itsasecret
--url http://hostname:15671/api/nodes/node001

A significant amount of JSON will be returned. Here is but a few of the commonly used key value pairs that should be returned.
