# StatsD Add-on

It listens for statistics such as counters and timers sent via UDP, performs aggregation of this data, then sends it on to a configurable backend service - such as Hosted Graphite. You can use StatsD to perform such aggregation before sending your metrics to us by following this short guide.

* Install StatsD by following the [installation instructions](https://github.com/etsy/statsd#installation-and-configuration).
* Once installed, StatsD can then be used with a config file like this:

```
{
    port: 8125,
    flushInterval: 10000,
    graphitePort: 2003,
    graphiteHost: "carbon.hostedgraphite.com",
    graphite: {
         legacyNamespace: false,
         globalPrefix: "your-api-key-here"
      }
}
```

### Hosted StatsD

Enable our Hosted StatsD if you don’t have the luxury of running a server yourself. Check out the [*Hosted StatsD*](/add-ons-and-integrations-guide/hosted-statsd.md) documentation.
