I have a federated link setup right now and it is delivering messages. I am watching the output of qpid-stat and watching the amount of bytes in and out. The federated link is going over a billable connection and I want to figure out how much data is going over the wire. I was watching the values on the exchange on the destination broker and calculating the size there (obviously just rough estimates for now) but then I noticed that several other exchanges are also going up in bytes in and out. The ones I have noticed to be constantly going up are qpid.management, qpid.default.topic, amq.direct, and qpid.default.direct. I am wondering why these exchanges are increasing in data used. I am not running any other management commands other than qpid-stat a couple times and the amount of messages on these exchanges are going up by thousands. My concern is that the federated link is generating a bunch of extra traffic on these other exchanges. Does anyone know if that is the case? Or is there something internal in qpid that is sending and receiving these messages on the other exchanges?
Those are management related messages caused by qpid-stat (and any other tools used, e.g. qpid-route). They are not going over the federated link (assuming you are not federating from any of those exchanges).
