> Currently we collect stats though JMX. Adding a new stat to JMX is
> cumbersome, and reading the stats out of JMX is painful if you're not on the
> same machine. As a consequence, we aren't measuring a fraction of the stuff
> we should be.
> There are a couple of nice stats packages out there, such as twitter-stats[1]
> and codahale metrics[2], which would make collection of stats much easier.
> This JIRA is to provide a generic interface, which a metrics backend can be
> plugged into.
