RabbitMQ - Count the number of messages in a queue using the REST API

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.

curl
--request GET
--user john.doe:itsasecret
--url https://hostname:15671/api/queues

 

Or, you can specify a single queue.

curl
--request GET
--user john.doe:itsasecret
--url https://hostname:15671/api/queues/vhost001/queue001

 

For the / vhost, use %2F.

curl
--request GET
--user john.doe:itsasecret
--url https://hostname:15671/api/queues/%2F/queue001

 

Something like this should be returned for each queue. Notice this output includes a number of "messages" keys.
