The Spotlight Diagnostic Server (by default) uses Extended Events to collect data from monitored SQL Server instances (SQL Server 2008 and above). The data is used by:
- SQL Server | Workload Analysis Drilldown
- SQL Server | Wait Events Drilldown
- Deadlock checks: SQL Server | SQL Activity Drilldown, Locks - Deadlocks Alarm.
Use this screen to either request that the Spotlight Diagnostic Server does not use Extended Events to collect data from monitored SQL Server instances or to customize the Spotlight Diagnostic Server use of Extended Events via advanced options.
