      Description

      I'd like to propose adding an API for reporting performance metrics. I will post some javadoc as soon as I figure out how to do so. The idea is for the API to be sufficiently abstract that various different implementations can be plugged in. In particular, there would be one that just writes the metric data to a file, and another that sends metrics to Ganglia. It would also be possible to plug in an implementation that can support high-frequency (say, per-second) sending of fairly large amounts of data (up to hundreds of metrics) across the network.

      I'd be very interested in people's thoughts about what the requirements should be for such an API.
