Dynatrace provides a set of pre-defined placeholders. Which of the following is one of them?

The correct choice highlights a predefined placeholder in Dynatrace that is widely utilized for tracking and analyzing user interactions. The sourceUrl placeholder is particularly significant as it allows users to capture the URL from which a session originated, thus enabling detailed insights into user behavior on the website or application. This is instrumental when assessing user navigation patterns, identifying popular entry points, and understanding the effectiveness of different marketing channels or referral links. By leveraging such placeholders, Dynatrace enhances its ability to provide meaningful data analytics that can drive better decision-making for performance optimization and user experience improvements.

Other options may represent parameters used within Dynatrace or application context but do not fall within the predefined placeholders that the platform regularly offers for monitoring and analysis.
