Benefits for Developers

Are your messages going where they should?

With QueueExplorer you can dig into your queues and see which message went where, whether they were correctly formatted, with correct headers and settings, etc.

Multiple viewers are at your disposal: JSON, XML, WCF, Hex, text with different encodings...

Develop and test producers and consumers separately

With QueueExplorer you can test individual pieces of your solution, or even simulate third party messages going in or out. You can create and edit test messages, send one by one or bunch of them together.

Test performance and load handling of your app

Send thousands of messages for performance testing to see how system handles that load.

Benefits for Admins

Troubleshoot, fix, and resend problematic messages

If something is wrong, QueueExplorer is the fastest and easiest way to investigate and fix incorrect, poison, or failed/deadletter messages.

See status of your system at glance

Check if some of queues are growing too large, if there are messages in deadletter queues, etc. With autorefresh functionality see how entire system works in near real time.

Filter and sort messages to quickly find important data

QueueExplorer allows you to quickly find messages you're interested in. Professional edition allows you to even extract your business data from within messages using XPath, JSON, or Regex, and to immediately see e.g. invoice totals, etc.

Backup and restore messages

Backup messages to files, or move/copy them to another queue.

Manage "hidden" messages

Azure Service Bus has two special kinds of messages - deferred and scheduled, which your applications normally don't see. With QueueExplorer you can check these messages, put them back in queue or reschedule them for another time.

Copy, compare and sync definitions of queues, topics, and subscriptions

This can be used to migrate queues (and other objects) to another namespace, e.g. to propagate from development to production. Or just to compare and see which changes were made. Or to backup schema before changes are made. You can also duplicate queues with all their settings on the same server (Professional).
