[rabbitmq-discuss] Presence Exchange Related Question

More specifically, for an application that provides a "presence" status, a
disconnect is something you want to capture and propagate accordingly. Is
one approach to do what you describe below (e.g. I could create a
consumer/service that keeps track of connects and disconnects and associate
that with a corresponding application context)? Is there something more
obvious on how this might be done with RabbitMQ?

Yes, you could do that (though you might have trouble correlating the
log messages with application-level entities). I don't think there's
anything much cleaner you could do using the built-in features, though.
Stepping away from built-ins, the presence exchange would probably
simplify things in terms of the code you'd need to write, but at the
cost of running a third-party plugin.

I have sometimes wondered about writing a plugin which just hooks this up
to an exchange, but I'm not sure how useful such a raw-ish stream would be.
Anyone?

Better than parsing the Erlang event log, for sure! I wouldn't even make
it a plugin, I'd make it a core feature, and hook up the monitoring using
the exchange per se.

Tony

Having a way for an application/consumer to subscribe to events stemming
from queue and connection drops would be very useful.

The management web UI shows this activity, but presumably it's polling
the http api and updating the screen data (i.e. I'm assuming it's
polling something because there's a select box "Update: every 5 seconds").
