Dyn’s RUM Beacon is a cookie-less, asynchronous, javascript code snippet which is embedded on a website to perform Real User Monitoring.  The code snippet currently measures content delivery networks (CDNs) from the perspective of end users, providing insight into how various major CDNs are performing to access networks around the world.


Implementing Dyn’s RUM Beacon is as simple as adding the following HTML to the head of your website.  Be sure to replace the data-id, XXXX, with the custom ID provided to you.  This beacon can also be easily implemented within your analytics tag manager of choice.

<script async src="https://dyn-beacon.akamaized.net/js/dyn.beacon.v4.js" id="beaconcfg" data-id="XXXX"></script>
