RabbitMQ deadletter queues and exchanges
QueueExplorer marks deadletter objects in a tree
If queue has a configured deadletter exchange, either directly in queue’s properties or through an associated policy, you can right click on one or more selected messages and choose “Move to deadletter”.
Displaying dead letter specific data
When working with queue’s message list, click on “Add/Remove columns” function from either a toolbar or a menu. You’ll find set of dead-letter related fields that can be displayed for each message: failure reason, retry count, original exchange, etc.
If you’re using QueueExplorer Professional, you can create separate “view” for deadletter queues, which will display appropriate DL columns for these queues, and skip them for others. See Queue Views
