Log File Auto Grow Event Class
The Log File Auto Grow event class indicates that the log file grew automatically. This event is not triggered if the log file is grown explicitly through ALTER DATABASE.
Include the Log File Auto Grow event class in traces that are monitoring the log file growth. When this event class is included in a trace the amount of overhead incurred will be low unless the log file is growing automatically frequently.
