[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance] The Data File Auto Grow event class indicates that the data file grew automatically. This event is not triggered if the data file is grown explicitly by using the ALTER DATABASE statement.
Include the Data File Auto Grow event class in traces that are monitoring growth of the data file.
When the Data File Auto Grow event class is included in a trace, the amount of overhead incurred is low unless the data file is growing automatically frequently.
