APM - Performance Tool - SQLs not shown

Hi, I recorded a session in APM-Performance Tool to capture a particular microflow, I know for certain that db queries are being made from this microflow and 'Record SQL statements' has been turned ON in APM, however nothing is shown under 'SQLs during this microflow' when I view this session. What could be the reason? Any ideas? Thanks, Kalyani

Changing the "SQL statement threshold (ms)" in the performance tool Filter will give more insights.
