This can be helpful to detect any current or potential problem areas, including automatic recovery messages (particularly if an instance of SQL Server has been stopped and restarted), kernel messages, or other server-level error messages.

Highlighted area “Logging SQL Server messages in file ‘C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\Log\ERRORLOG’” is current ERRORLOG file. Typically, SQL Server retains backups of the previous six logs and gives the most recent log backup the extension .1, the second most recent the extension .2, and so on. The current error log has no extension.
