<p>By convention it will have a <code>msg.payload</code> property containing
the body of the message.</p>
<p>If your node need to log anything use the <code>node</code> object:
<ul>
<li>Info: <code>node.log(msg);</code></li>
<li>Warning: <code>node.warn(msg);</code></li>
<li>Error: <code>node.error(msg);</code></li>
