I think that would be a really useful addition for Rabbit.<br><br>A topic exchange named something like amq.admin or <a href="http://amq.broker.info">amq.broker.info</a> that has internal consumers listening to several queues whose bindings correspond to a standardized set of messages and routes info messages to a response exchange appropriately.<br>
<br>Just some off the cuff ideas:<br><br>amq.admin.listVirtualHosts.[pattern]<br>amq.admin.listUsers.[pattern]<br>amq.admin.listPrivileges.(user)<br>amq.admin.listExchanges.vHostName.[pattern]<br>amq.admin.listQueues.exchangeName.queueName.[pattern]<br>
amq.admin.listQueues.exchangeName.binding.[pattern]<br>amq.admin.getMessageCount.queueName<br><br>where pattern might be a simple matching expression.<br>ex: if you sent a message with the routing key amq.admin.listVirtualHosts.Rabbit* you would get back a message with a list of all virtual hosts whos ename starts with "Rabbit".<br>
<br><br>So it might be like this, at a high level....<br><br>RabbitMQ server:<br>amq.admin - Topic exchange<br> has a set of queues bound with routing keys corresponding to each command<br> each queue has an internal consumer process listening. These processes will use rabbit_control to get the requested info and construct a response message.<br>
client messages should have a "secret" routing key in the payload (see below) so the consumers know where to route their response.<br><br>amq.admin.response - Direct exchange<br> clients bind exclusive queues with a "secret" routing key that they send in the payload of their messages to amq.admin<br>
the internal consumer processes route their response messages to this exchange with the "secret" key the client sent in their message.<br><br><br><br><br><br><div class="gmail_quote">On Wed, Apr 22, 2009 at 1:32 PM, Matthias Radestock <span dir="ltr"><<a href="mailto:matthias@lshift.net">matthias@lshift.net</a>></span> wrote:<br>

Are there any reserved exchange or routing namespaces for the<br>
implementation itself?<br>

No, though a pretty safe bet is to use the "amq." namespace, which is reserved for "predeclared and standardised exchanges". So, for example, rabbit's internal log exchange is named "amq.rabbitmq.log".<br>
