4.2 has a command agent...
http://activemq.apache.org/command-agent.html

which can be used for sending simple text commands to the broker and getting replies - such
as to enquire about queue depths and the like.

There's also advisory messages...
so you can listen to the operation of the broker, seeing new destinations, consumers, producers
etc.

However we've never yet wrapped up a little easy API folks can use on the client to easily
view the available destinations and get their stats etc.


Something like the following...

{code}
Collection<ActiveMQQueue> connection.findQueues()
Collection<ActiveMQTopic> connection.findTopics()

// look up stats like queue depth etc
DestinationStats getDestinationStatistics(ActiveMQDestination);
{code}
