loggly-winston.js

var winston = require('winston'),
    loggly = require('loggly');

var client = loggly.createClient({
  subdomain: "your-subdomain",
  auth: {
    username: "your-username",
    password: "your-password"
  }
});

client.getInputs(function (err, inputs) {

  var input = inputs.filter(function (i) { return i.name === 'your-input-name' })[0];

  winston.add(winston.transports.Loggly, {
