The SQL baseline must be captured during the test and not after, as done for the reports on aggregated data, because a DB2 statement event monitor is started to capture the data.

Once we collected some of this baseline data using the performance Monitor and the Probe workload, we also tried varying different Settings to see if we could detect an improvement in performance.

If the test you want to take a baseline on is running at night, you can schedule the report generation and the collection of SQL event monitor data by the DB2 statement event monitor.
