  StatsD route monitoring middleware for Connect/Express. This middleware can be used either globally or on a per-route basis (preferred) and sends status codes and response times to StatsD.
  npm install express-statsd
  An example of an express server with express-statsd:
  var express = require('express'); var expressStatsd = require('express-statsd'); var app = express();
  app.use(expressStatsd());
  app.get('/', function (req, res) { res.send('Hello World!'); });
  app.listen(3000);
  By default, the middleware will send
  status_codeand
  response_timestats for all requests. For example, using the created server above and a request to, the following stats will be sent:
  status_code.200:1|c response_time:100|ms
  However, it's highly recommended that you set
  req.statsdKeywhich will be used to namespace the stats. Be aware that stats will only be logged once a response has been sent; this means that
  req.statsdKeycan be set even after the express-statsd middleware was added to the chain. Here's an example of a server set up with a more specific key:
  var express = require('express'); var expressStatsd = require('express-statsd'); var app = express();
  function statsd (path) { return function (req, res, next) { var method = req.method || 'unknown_method'; req.statsdKey = ['http', method.toLowerCase(), path].join('.'); next(); }; }
  app.use(expressStatsd());
  app.get('/', statsd('home'), function (req, res) { res.send('Hello World!'); });
  app.listen(3000);
  A GET request to
  /on this server would produce the following stats:
  http.get.home.status_code.200:1|c http.get.home.response_time:100|ms
  This module also works with any
  httpserver
  var http = require('http'); var expressStatsd = require('express-statsd');
  var monitorRequest = expressStatsd();
  http.createServer(function (req, res) { monitorRequest(req, res);
  // do whatever you want, framework, library, router res.end('hello world');
  }).listen(3000);
  expressStatsd(options);
