How many key user actions can be defined per application in Dynatrace?

In Dynatrace, you can define up to 20 key user actions per application. Key user actions represent the most critical interactions that users have with your application, such as clicking on a button, completing a form, or navigating to a specific page. By tracking these actions, teams can better understand user behavior, identify performance bottlenecks, and enhance the overall user experience.

The limit of 20 allows comprehensive tracking of essential interactions without overwhelming the analysis, ensuring that developers and business stakeholders can focus on the most impactful actions. Having a well-defined set of key user actions also enables easier correlation with performance metrics and user experience metrics.

Thus, the correct answer is 20, as it aligns with Dynatrace's design to promote meaningful insights while maintaining data manageability.
