Hi,
The fact that you can easily look at the Delayed message queue and its content is fine, however some of our customers would like to have an option that they can set some kind of threshold for the delayed message queue.
When it reaches a certain amount of retries or the queue suddenly fills up with more than couple of hundred messages, that they can then get an email notification to multiple recipients or help desk email address.
Currently there is alerts on queues but it is either on/off and you cannot set the threshold or trigger for a notification
