## Documentation

Docs can be found here: http://lanceball.com/rhq-metrics-middleware

## Usage

    // load the RHQ middleware module

    var rhq = require('rhq-metrics-middleware');

    var express = require('express');

    var app = express();

    app.set('port', 9000);

    // Use the rhq-metrics-middleware module.

    // By default the module will insert the following data:

    // load-1: 1 minute load average. See `os.loadavg()`

    // load-5: 5 minute load average. See `os.loadavg()`

    // load-15: 15 minute load average. See `os.loadavg()`

    // free-memory: Current free memory. See `os.freemem()`

    // response-time: Response time for the current request.

    app.use(rhq({

      host: 'metricserver.mydomain.com', // default is localhost

      port: 4567, // default is 8080

      path: '/rhq-metrics/metrics' // default

      }));

    app.get('/*', function(req, res) {

      res.send('Well hello there');

    });

    var server = app.listen(app.settings.port, function () {

      var addr = server.address();

      console.log('listening at http://%s:%s', addr.address, addr.port);

    });
