Why might custom metric data not be visible in Data Explorer for user sessions?

Custom metric data may not be visible in Data Explorer for user sessions because session metric data is not extracted until a connection is closed. In the context of monitoring and analyzing user sessions, Dynatrace processes and aggregates data for analysis once the session is completed. This means that real-time visibility into session metrics can be limited until the user session ends and the data is finalized for storage and analysis.

This mechanism ensures that the captured metrics accurately reflect the entire duration of the user interaction, rather than only partial or incomplete data that may occur while the session is still active. Waiting for the session to close allows for a more reliable and comprehensive analysis of the user experience, which is essential for effective monitoring and troubleshooting.

Other reasons, such as configurations or data collection issues, could affect visibility in different contexts, but they do not specifically address the point of when and how session metric data becomes available for analysis in Data Explorer.
