Or Identifying SQL Server Error Log File used by SQL Server Database Engine can be done by reading SQL Server Error Logs. DBA can execute the XP_READERRORLOG extended stored procedure to read the SQL Server Error Log and search for its location used by the instance of SQL Server.
xp_readerrorlog 0, 1, N’Logging SQL Server messages in file’, NULL, NULL, N’asc’
The parameters for XP_READERRRORLOG are:
1. Value of error log file we would like to read. values are 0 = current, 1 = last one before current, 2 = second last before current etc…
2. Log file type:- 1 or NULL = error log, 2 = SQL Agent log
3. Search string 1:- String one you want to search for
4. Search string 2:- String two you want to search for to further refine the results
5. start time for Search
6. end time for search
7. Sort order for search results:- N’asc’ = ascending, N’desc’ = descending
By default, we have 6 Server Error Logs kept but we can increase the number of SQL Server Error Logs from the default value of six.
