Which component is essential for real-time monitoring of user interactions as per the manual/Agentless injection?

The JavaScript tag is crucial for real-time monitoring of user interactions in web applications. By embedding this tag in the pages of a website, it allows the Dynatrace platform to collect data directly from the user's browser. This data includes user behavior metrics, such as page views, clicks, and other interactions that occur in real time.

Using the JavaScript tag enables Dynatrace to understand how users interact with the application, identify performance bottlenecks, and track specific user sessions. This is essential for delivering a comprehensive view of user experience, which is vital for optimizing application performance and ensuring high user satisfaction.

In contrast, components like OneAgent are more suited for monitoring backend services, while server-side applications focus on tracking server performance. Browser plugins can enhance user experience but are not specifically designed for extensive monitoring of user interactions in the same way that the JavaScript tag performs.
