Compared to Graphite, installing StatsD server is just a piece of cake.

1. Install Node.js. For better management on Node.js, you could consider using nvm.

 

2. Checkout the StatsD project on GitHub.

git clone https://github.com/etsy/statsd.git

 

3. Copy the exampleConfig.js and name it to whatever you like and edit it as follow.
ex. statsdConfig.js.

{
  graphitePort: 2003
, graphiteHost: "<graphite host>"
, port: 8125
, backends: [ "./backends/graphite", "./backends/console" ] // console is for debug
, debug: true // For debug
, graphite: { legacyNamespace: false } // Better group all collected metrics under stats
}
