SQL Inspector > Inspect

After adding or modifying an Inspector in the SQL Inspector window, SQL statements and statistics from the monitoring tables are retrieved by executing the Inspect function.

To start the inspecting process

Click image\B_Inspect.gif.

If the start time of the Inspector has not been reached, the SQL Inspector waits until it is time to begin. During and at the end of the inspecting, information is updated on the SQL Inspector window. Inspect terminates automatically once the end time is reached, except for ad-hoc inspecting. The ad-hoc inspecting process has no ending time so it must be terminated manually.

To abort the inspecting

Click image\B_AbortInspect.gif.

Note: If you have already executed the Inspect function for an Inspector, re-executing the Inspect function will erase all existing information.
