You work for MDFT Pro, a well-known training agency that processes real-time student activity data. Mark, a Real-Time Analytics Engineer at MDFT Pro, manages an eventstream called StudentActivityStream that captures student quiz submissions, video completions, and forum interactions from the learning management system. The eventstream includes several transformations to enrich the data, filter out test accounts, and calculate engagement scores before routing the data to a KQL database and Power BI reports. Recently, Mark discovered that one of the transformations in StudentActivityStream is failing intermittently, causing some student activities to be lost. He needs to investigate the issue by finding detailed error information including the exact error messages, when the errors occurred, and any warnings that might indicate the root cause. This information will help him determine whether the failures are due to malformed input data, incorrect transformation logic, or resource constraints.
What should Mark use to find the error details, including the occurrence time?
