There was several previous discussions on metrics for the new clients but I'm not sure had a unanimous consensus on the best approach. I'd put forward the following options: 1. Plain vanilla JMX (no one actually wanted this, but for completeness...) 2. Improve on custom metrics package current on trunk 3. Coda Hale package
There are of course many other possibilities, but we didn't get a concrete alternative so let's just vote on these and do one of them so we can keep making progress.
For my part I am +1 for (2). I agree it is a bit of NIH, but I think the advantages of the new code combined with the advantages of a no-deps client are worth it.
