Which method is used by Dynatrace to inject the RUM JavaScript tag during monitoring?

Dynatrace utilizes application detection rules to inject the RUM (Real User Monitoring) JavaScript tag on monitored applications. These rules are configured to identify the specific web applications that require monitoring and to embed the necessary JavaScript code into the pages of those applications automatically. By utilizing these rules, Dynatrace can effectively place the RUM tag in the right context, ensuring that the tag loads correctly when users access the web application.

This method allows for customization and flexibility, as application detection rules can be tailored to various conditions and attributes of the applications being monitored. Consequently, this process improves the accuracy of user data collection and the overall performance analysis of the web applications.

Other choices, such as layout management, user authentication, and session tracking, address different aspects of application performance monitoring and user experience but do not pertain directly to how the RUM JavaScript tag is injected into the web application. These elements serve specific functions within the ecosystem of a web application but are not the primary method for inserting monitoring tags.
