StatsD backend to emit stats over

StatsD backend to emit stats over This backend allows you to subscribe to individual stats, groups of stats, or all stats and handle them in real time.

There are a few ways to install to be used as a StatsD backend. You can add it to the StatsD package.json and run npm install.

The simplest way to install the module is to run:

  $ npm install

To add this backend to the StatsD daemon, simply add the following settings to the StatsD configuration file:

  socketPort: 8000,
  backends: ['']

If you want to keep the graphite backend installed, you need to include './backends/graphite' in the backends configuration.

var socket = require('').connect('http://localhost:8000');
socket.on('connect', function () {
  socket.emit('subscribe', 'all');
  socket.emit('subscribe', 'timers');
  socket.emit('subscribe', 'gauges.server1.cpu');
  socket.emit('subscribe', 'gauges.*.cpu');
// Retrieve all stats 
socket.on('all', function (data) {
  console.log('ALL:' + data);
// Retrieve a groups of stats 
socket.on('timers', function (data) {
// Retrieve a single stat 
socket.on('gauges.server1.cpu', function (data) {
  console.log('Server1 CPU:' + data);
// Supports wildcards 
socket.on('gauges.*.cpu', function (data) {
  for (var server in data.gauges) {
    console.log(server + ' CPU:' + data.gauges[server]['cpu']);

This example shows using on the server side but can just as easily be implemented on the client side. See the documentation for more information.

To run the tests:

npm test
