# StatsD

> statsD is a network daemon that runs on the [Node.js](http://nodejs.org/) platform and listens for statistics, like counters and timers, sent over [UDP](http://en.wikipedia.org/wiki/User_Datagram_Protocol) or [TCP](http://en.wikipedia.org/wiki/Transmission_Control_Protocol) and sends aggregates to one or more pluggable backend services (e.g., [Graphite](http://graphite.readthedocs.org/)).\
