What is Automatic agent injection (RUM) primarily responsible for?

Automatic agent injection for Real User Monitoring (RUM) plays a crucial role in simplifying the setup process for monitoring web applications. Its primary function is to seamlessly inject JavaScript tags into the HTML of web pages served by monitored applications. This enables the collection of user interaction data directly from browsers as users navigate through the application.

By automatically injecting these tags, the process reduces the need for manual intervention and ensures that monitoring is consistently applied across all user sessions and application updates. This capability allows Dynatrace to capture essential data such as page load times, user interactions, and performance metrics, which can be critical for analyzing and enhancing the user experience.

The other options, while relevant to various aspects of application performance management, do not pertain specifically to the core functionality of automatic agent injection in RUM. Therefore, the ability to inject JS tags into HTML from monitored servers is the defining responsibility of this feature.
