End-user experience performance metrics

The end-user experience (EUE) metrics enable you to monitor and measure the performance of your web-based applications from the perspective of your users. These metrics measure the duration of page navigation events, which enable you to identify areas of concern or interest.

Where can I see these metrics?

To see EUE metrics in TrueSight Intelligence, you must add the JavaScript snippet to your application. Use the search to find the metrics and see their values, or use the Sources menu to view the metrics associated to the App.
