Basing more and more stuff on mcollective means relying more and more on one of its underlying components : the activeMQ middleware, and more precisely the stomp connector. I hit a weird bug a few days ago and realized that I was not functionnaly monitoring this part of the system. The port was bound and responded to connections, subscriptions were possible but messages didn’t pass through.So I wrote this little plugin that makes this possible : it creates a random string, sends it to a queue and then reads the queue to check if the result is the same.
This has been possible with the help of @ripienaar. Thanks for the explanation for the difference between topics & queues !
