<p>To view the component descriptor, you may <br>

<code>curl -s https://<?= h($_SERVER['SERVER_NAME']) ?>/descriptor</code></p>
|

This will return the entire JSON descriptor variable.<br>

The endpoint agent uses this descriptor to build out its local System Object.<br>
|

The agent then reports back to the Cosmostat Server with all the data found in the descriptor.<br>
