I have AppInsight setup for a 2016 exchange server, I am trying to figure out settings to see the message queue with no luck. Anyone have any guidance on this?
Have you tried adding a PowerShell monitor component? You could do something like "Get-Queue | measure" to get the count of messages in the queue.
Another option would be to use the "\MSExchangeTransport Queues(_total)\Aggregate Delivery Queue Length (All Queues)" performance counter.
