Tips to using this grid
- Click a session in the grid for more details on the session.
- Many applications create multiple connections to SQL Server.
- When there are more than 2000 sessions only those sessions that are active (and those sessions that are blocked and blocking) are shown.
- To show only those sessions that are currently executing, click Show active sessions only.
- To close a SQL Server session, right click and select Kill this session. This option is available only to members of the Spotlight Diagnostic Administrators group.
