What component indicates that new actions can be added to a session in Dynatrace?

The arrowhead at the end of the timeline is an important visual indicator in Dynatrace that signifies the potential for further user interactions within a session. This graphical element suggests that there is the possibility of additional actions being recorded or indicated beyond the current displayed timelines. When users see this arrow, it implies that the session is still active or capable of tracking further user actions, making it a critical component for understanding user behavior during sessions.

In contrast, the other options do not serve this specific function. The color scheme of the session may indicate different states or types of performance metrics, but it does not convey the ability to add new actions. The duration of the session provides information about how long the session has been active, but it does not indicate the potential for new actions to be added. The number of user actions recorded reflects the data already gathered but does not suggest whether additional actions can still be captured. Thus, the arrowhead uniquely signifies that more actions can be incorporated into the session's timeline.
