+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:
+
+* stats - some stats about the running server
+* counters - a dump of all the current counters
+* timers - a dump of the current timers
+
+The stats output currently will give you:
+
+* uptime: the number of seconds elapsed since statsd started
+* graphite.last_flush: the number of seconds elapsed since the last successful flush to graphite
+* graphite.last_exception: the number of seconds elapsed since the last exception thrown whilst flushing to graphite
+* messages.last_msg_seen: the number of elapsed seconds since statsd received a message
+* messages.bad_lines_seen: the number of bad lines seen since startup
+
