Retrieving number of unacknowledged messages in RabbitMQ queue from Java/ Spring

Question

is there any way to return the number of messages that are unacknowledged?

I am using this code to get the number of messages in the queue:

DeclareOk dec         


        

Answer 1

As you say in your update, if you enable the management plugin, you can query the rest api:

Eg:

`http://username:password@queue-server:15672/api/queues/%2f/queue_name.queue`

This returns json with (among other things)

• messages_unacknowledged
• messages_ready

It's good stuff if you have a safe route to the server.

actual url for 3.8.9 version:

http://username:password@queue-server:15672/api/queues/%2F/queue-name
