Monitoring enduser experience through RUM (Real User Monitoring) requires the use of either a JavaScript (the App-Watcher) or a browser's extension (the User-Watcher).

The App-Watcher is included in the <HEAD> section of your monitored page HTML code. It is executed on the user's browser to instruct it to send performance metrics to the Kadiska platform.

In order to prevent any performance impact this JavaScript may have on your overall web performances, this is delivered by Kadiska through a CDN (Content Delivery Network). Furthermore, you may chose to use techniques like defer or async that make sure loading this JavaScript will not block the HTML parsing process.

This Kadiska App-Watcher is configured in the Watcher section.
