Artemis Address Message Count

abhijith
Hi,

We are monitoring Artemis via JMX.  We have a topic(address with multicast) which has a divert to a queue.  If I send messages to this address messages gets diverted correctly to queue.  But if I query address mbean both messageCount and noOfMessages is 0.  

Is this expected?  I think address should have messageCount regardless of queue or a divert associated with it.  Currently I cannot get no of messages sent to an address.  The only way I can get it is to pull binding names and loop through them.

When you get the message count for an address it sums the message count for all the queues bound directly to that address.  In the case of a multicast address that would be, for example JMS subscriptions, explicitly configured queues (from broker.xml), etc.  This does not include queues receiving messages sent to the address via a divert.  Therefore, if you don't have any queues specifically bound to the address then I would expect a 0 message count.

Thanks Justin.  But IMHO it is misleading behavior..right?  As publisher I would like to get count of no of messages sent to an address.  Publisher won't worry about how many queues or diverts are associated to an address.

Right now if queues are not associated with an address, there is no way to directly get a message count.

I don't think it's misleading.

We don't currently track the total number of messages sent to an address.  The message count is just the number of message currently residing in the queues bound to the address.

I suppose that depends on the publisher.

I don't believe there actually is a way for a queue to not be associated with an address.  In other words, a queue is always associated with an address.  When you configure a divert you configure the "forwarding-address" where the messages are sent which in turn will send those messages to the queues associated with that address according to the configured semantics (i.e. anycast or multicast).  You can check the message count of this address if you like.  You can also check the message count for any queue as well.

Thanks for the information Justin. I am counting numbers on all the diverts now and will continue with that.
