title: Command to display all delivered messages to a Mosquitto Broker?
body: <p>I have been using following command to see published messages on the Mosquitto broker:</p>
  <pre><code>mosquitto_sub -h IP_ADDRESS -t TOPIC_NAME
  </code></pre>
  <p>However, when I run this command I can see only the recent messages not all published messages. In Mqtt client, I can see messages delivered.</p>
  <ol>
  <li>Is there a command to see all messages that were delivered to the broker?</li>
  <li>The command only shows messages when we start subscribing?</li>
  </ol>
  <p>I have used value 2 for Quality of Service in message properties.</p>
