Explanation:
The Blocked Process Report event class indicates that a task has been blocked for more than a specified amount of time. This event class does not include system tasks or tasks that are waiting on non deadlock- detectable resources.
To configure the threshold and frequency at which reports are generated, use the sp_configure command to configure the blocked process threshold option, which can be set in seconds. By default, no blocked process reports are produced.
