Data File Auto Shrink Event Class
The Data File Auto Shrink event class indicates that the data file has been shrunk. This event is not triggered if the data file shrinks because of an explicit ALTER DATABASE statement. Include the Data File Auto Shrink event class in traces that monitor the data file size changes.
When the Data File Auto Shrink event class is included in a trace, the amount of overhead incurred is low unless the data file frequently shrinks.
