-Many users have been confused to see their hit counts averaged, missing when the data is intermittent, or never stored when statsd is sending at a different interval than graphite expects.  Storage aggregation settings will help you control this and understand what Graphite is doing internally with your data.

 TCP Stats Interface

-A really simple TCP management interface is available by default on port 8126 or overriden in the configuration file. Inspired by the memcache stats approach this can be used to monitor a live statsd server.  You can interact with the management server by telnetting to port 8126, the following commands are available:

-A test framework has been added using node-unit and some custom code to start and manipulate statsd. Please add tests under test/ for any new features or bug fixes encountered. Testing a live server can be tricky, attempts were made to eliminate race conditions but it may be possible to encounter a stuck state. If doing dev work, a `killall node` will kill any stray test servers in the background (don't do this on a production machine!).
