What indicates that a web application is successfully enabled with Real User Monitoring (RUM)?

The indication that a web application is successfully enabled with Real User Monitoring (RUM) primarily hinges on the presence of a specific JavaScript agent script tag within the web page source. This script tag is essential because it is what establishes a connection between the user's web activity and the monitoring platform, allowing for the collection of real user interactions and performance data.

When the JavaScript agent is integrated correctly, it captures a variety of performance metrics and user behavior insights, which are sent back to the Dynatrace monitoring service. This enables detailed analytics, such as page load times, user interactions, and other critical performance indicators that contribute to a more profound understanding of user experience and application performance.

The other options do not serve as reliable indicators of successful RUM implementation. For instance, simply having the homepage load correctly does not guarantee that monitoring is active; it only shows that the site is operational. High traffic alone does not imply monitoring is taking place; it indicates user engagement without reflecting on the data collection itself. While passing performance metrics is important for overall application health, it does not directly correlate with the proper implementation of RUM, as one can achieve acceptable performance metrics without having RUM set up. Therefore, the presence of the JavaScript agent script tag is
