How is user session duration defined in Dynatrace?

The correct understanding of user session duration in Dynatrace is defined as the time between the first action and the last action in a session. This definition captures the entire span of user interactions within a given session, providing a comprehensive view of user engagement with the application. It accounts for all actions that a user takes during their session, making it a holistic measure of user activity.

This approach to defining session duration is crucial for analyzing user behavior, as it allows organizations to see how long users are actively engaging with the application from start to finish. By considering the first and last actions, it addresses the full range of user interaction, ensuring that both initial engagement and exit points are reflected in the session metrics.

Other definitions, such as those focused solely on specific actions like spending time on the homepage or only counting active interactions, do not provide as complete a picture. This is because they could omit valuable interactions that occur during the session but are not the first or last actions, or they might not adequately account for all user activity.
