Network daemon for the collection and aggregation of realtime application metrics

# Supported Backends

StatsD supports pluggable backend modules that can publish
statistics from the local StatsD daemon to a backend service or data
store. Backend services can retain statistics in a time series data store,
visualize statistics in graphs or tables, or generate alerts based on
defined thresholds. A backend can also correlate statistics sent from StatsD
daemons running across multiple hosts in an infrastructure.

StatsD includes the following built-in backends:

* [Graphite][graphite] (`graphite`): An open-source
  time-series data store that provides visualization through a web-browser.
* Console (`console`): Outputs the received
  metrics to stdout (see what's going on during development).
* Repeater (`repeater`): Utilizes the `packet` emit API to
  forward raw packets retrieved by StatsD to multiple backend StatsD instances.

By default, the `graphite` backend will be loaded automatically. Multiple
backends can be run at once. To select which backends are loaded, set
the `backends` configuration variable to the list of backend modules to load.

Backends are just npm modules which implement the interface described in
section [Backend Interface](./backend_interface.md). In order to be able to load the backend, add the
module name into the `backends` variable in your config. As the name is also
used in the `require` directive, you can load one of the provided backends by
giving the relative path (e.g. `./backends/graphite`).

A robust set of are also available as plugins to allow easy reporting into databases,
queues and third-party services.
