The Sessions grid shows all SQL Server sessions, each row representing a single SQL Server session.

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.
  • The screen refreshes automatically. To pause Auto Refresh click Pause Auto Refresh. Click again to re-start auto refresh.
  • The status column of the grid is color coded for readability.
  • You can view more details for a session by clicking it in this grid. Additional pages are then displayed in the lower half of the drilldown.
