Is there any way to see the unacknowledged message?

[Chetan Ghodasara]

Hello,

We have 1 producer & 1 consumer of this queue. Consumer's manual ack is enabled.
But many times, RabbitMQ shows 1 unacknowledged message. & Next all coming messages are just piled up in the queue. I think due to this unacknowledged message, next messages are not being consumed.

(1) Is there any way I can see the unacknowledged message?
(2) Currently, if I restart the consumer, the unacknowledged message will be requeued. But Is there any way, we can requeue this unacknowledged message without restarting the consumer?

Thanking you

1. There is no. You cannot consume a message twice with any of the protocols RabbitMQ supports.

2. Close its channel (which will automatically cancel all consumers on it) or connection (closes all channels on it and therefore cancels all consumers).

It's the channel closure that results in requeueing of unacknowledged messages [1], not application restart per se.
