I could be wrong, but i have spent quite some time researching this. Basically this is the scenario: 1.) There is a Game Server which uses ActiveMQ (Server sends messages to specified queue's/topic's) 2.) There are Game Clients (Among other kinds of clients). 3.) There is a message consumer (basically it takes the messages off the queue and stores the necessary information in a table (db). The Server and some of the "clients" are java based, where as others are python based. What i need to accomplish is a way to monitor: * How Many Consumers are Connected (If none, maybe pause messages, probably store them in cache or something until someone is available to receive them) * The size of a actual queue or topic (Its quite easy to crash ActiveMQ with a GB or more worth of messages). What i am trying to accomplish is to find a way to do this in one of the python clients, its somewhat of a system monitor: Monitors if AMQ is running, consumer... stuff like that ... as well as the definite "AMQ Resources themselves"... now after reading up on Advisory Messages if i had a way to directly access: If a topic/queue is full - The link that you showed above does give some definite suggestions (in java) for how i would do something like this. One question that i have is, is it possible to subscribe to an advisory topic (I personally have tried to no avail). Given i'd like to be able to check for this advisory message if possible: advisoryWhenFull.. "ActiveMQ.Advisory.FULL" As well as Accessing Consumer/Producer count via the advisory messages: ActiveMQ.Advisory.Producer.Queue ActiveMQ.Advisory.Producer.Topic ActiveMQ.Advisory.Consumer.Queue ActiveMQ.Advisory.Consumer.Topic See reference link below: http://activemq.apache.org/advisory-message.html Advisory Message ----- “A foolish man tells a woman to stop talking, but a wise man tells her that her mouth is extremely beautiful when her lips are closed” -- View this message in context: http://www.nabble.com/PyActiveMQ%3A-Retrieving-Queue-Size-%28Or-other-Queue-related-info%29-tp21460541p21501488.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
