Both collectors used TOP N ORDER BY total_elapsed_time DESC with no time filter, so long-running cached plans (e.g. HammerDB) permanently occupied all slots and recently-executed queries were never collected. Added last_execution_time >= DATEADD(MINUTE, -10, GETDATE()) filter to both collectors (all query variants including Azure SQL DB). Bumped query_stats TOP from 50 to 200 to capture more active queries per sweep. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
