title: In Azure IoT hub - where do i see MQTT messages that has been sent from a device?
body: <p>im trying to send messages over the MQTT protocol to Azure IOT hub. 
  Im using this code in NodeJS:</p>
  
  <pre><code>var clientFromConnectionString = require('azure-iot-device- 
  mqtt').clientFromConnectionString;
  var Message = require('azure-iot-device').Message;
  
  var connectionString = 'HostName=myhostname.azure- 
  devices.net;DeviceId=Arsenal;SharedAccessKey=mysharedaccesskey';
  
  var client = clientFromConnectionString(connectionString);
  
  
  var connectCallback = function (err) {
    if (err) {
      console.error('Could not connect: ' + err);
    } else {
      console.log('Client connected');
      var message = new Message('some data from my device');
      client.sendEvent(message, function (err) {
        console.log("Message sent!");
        if (err) console.log(err.toString());
   });
  
  client.on('message', function (msg) {
    console.log(msg);
    client.complete(msg, function () {
      console.log('completed');
     });
    });
   }
  };
  
  client.open(connectCallback);
  </code></pre>
  
  <p>This prints "Client connected!" and "Message sent!"
  Maybe this is a really silly question, but where in IoT Hub can i see the message that has been sent?</p>
