If I'm using JConsole, where would I see it in that GUI?

The scheduler is a KahaDB based store that is used to hold and manage the scheduled messages
for the broker.  If you are using the broker side redelivery plugin then there could be messages
store in the scheduler. 
You can use the JMX MBean to query what is contained in the scheduler.
