So I know this is a little late and a solution has already been found but here is another way to look message counts in your queues

This solution assumes that you are using the spring rabbitmq framework and have defined your queues in your application config with the following tags defined

The java class:

public class QueueStatsProcessor {
    @Autowired
    private RabbitAdmin admin;
    @Autowired
    private List rabbitQueues;

    public void getCounts(){
        Properties props;
        Integer messageCount;
        for(Queue queue : rabbitQueues){
            props = admin.getQueueProperties(queue.getName());
            messageCount = Integer.parseInt(props.get("QUEUE_MESSAGE_COUNT").toString());
            System.out.println(queue.getName() + " has " + messageCount + " messages");
        }
    }
}

You can also use this solution to read the current consumers attached to the queue http://docs.spring.io/spring-amqp/docs/1.2.1.RELEASE/api/org/springframework/amqp/rabbit/core/RabbitAdmin.html#getQueueProperties(java.lang.String)
