Hi all, I'm curious about the statistics maintained on the broker. In particular I've been sending messages to the amq.match exchange and binding to a queue. Now I've deliberately set it up such that my binding only matches 2/3 of the messages I'm sending but looking at some of the stats from QMF there's a bit of oddness.
Looking at the enqueues and dequeues these seem to match what I'd expect, but looking at the exchange stats the number of messages looks wrong - both the msg receives and messages routed look a bit low. The messages routed ought to tie up to the number of messages enqueued but it doesn't. Are there any gotchas I should be aware of. I've been using RedHat's Cumin user interface to look at this stuff (just started playing around with Cumin it looks pretty useful) I guess it could be something to do with Cumin's polling but I refreshed for a while after I stopped sending messages and things didn't change. It would be good to be able to account for this as I'm tempted to go down the Cumin route as some of my users just have to have some eye candy, but I don't want to confuse matters with misleading stats. On a related note I see that the exchange stats record msg drops, which presumably is the number of "unroutable" messages due to there being no matching binding - that has got me thinking. Is there any way to actually deliver messages that don't match an explicit binding on an exchange to a default queue (I'm particularly interested in this for the headers exchange). Finally although Cumin seems quite good (though a bit of a fight to get running on Ubuntu) I was interested in other options for a GUI for the C++ broker is anything else out there? What's the approach actually recommended by the Qpid community?
