[rabbitmq-discuss] current queue size is always different with a real queue size. actually, it is always same with actual queue size - prefetch size.

[Henry JunYoung Kim]

hi, 

I am a newbie to use a rabbitmq. 

currently, I am using it without no auto-ack mode. 

manually, I send  ack/nack after receiving messages from queues.

but, on this, I found that current queue size is always different with a 
real queue size. actually, it is always same with actual queue size - 
prefetch size. 

here is my code to send. 

        channel.basicPublish(exchangeName, queueName, *null*, message);

        System.out.println(channel.queueDeclarePassive(queueName).getMessageCount()); 
// for debugging

If I set the prefetchCount as 5. it prints out 

0

0

0

0

0

1

2

3

4

.....

If I set it as 3, it prints out

0

0

0

1

2

3

4

..


How could I retrieve the correct queue size regardless of the prefetchCount.


thanks for your concerns.
