What purpose do session and user action properties serve in application performance analysis?

Session and user action properties play a crucial role in application performance analysis by allowing for detailed insights into user behavior and system performance. By facilitating fine-grain user-session and application-performance analysis, these properties enable teams to pinpoint exactly how users interact with the application, identify potential bottlenecks, and measure specific user actions that might impact performance.

The use of session properties helps in understanding the context of user engagement, such as the duration of sessions, paths taken within the application, and any errors encountered, which assists in directly correlating user experiences with performance metrics. This level of analysis is essential for improving both the user experience and overall application performance, making it possible to tailor optimizations based on actual user interactions.

Thus, option B stands out as it highlights the functionality of session and user action properties in delivering actionable insights that lead to enhanced performance analysis.
