Error log folder location and OLA's SQL maintenance solution

Question

Looking at one of our dev sql servers, it has a -e startup parameter to define the error log folder at this location : E:\DATA\MSSQL13.MSSQLSERVER\MSSQL\Log\ERRORLOG. However, only E:\DATA\MSSQL13.MSSQLSERVER\MSSQL exists on disk. I can see Ola's SQL maintenance output files on disk at E:\DATA\MSSQL13.MSSQLSERVER\MSSQL\Log

Who / what is responsible for creating the error log folder as defined by the -e startup parameter?

Does OLA's maintenance solution have a fallback if it can't find the log folder defined with -E startup parameter?

Answer 1

All the code is on github There is quite a lot of it now github link

IF @Version >= 11
 BEGIN
 SELECT @LogDirectory = [path]
 FROM sys.dm_os_server_diagnostics_log_configurations
 END
ELSE
 BEGIN
 SELECT @LogDirectory = LEFT(CAST(SERVERPROPERTY('ErrorLogFileName') AS nvarchar(max)),LEN(CAST(SERVERPROPERTY('ErrorLogFileName') AS nvarchar(max))) - CHARINDEX('\',REVERSE(CAST(SERVERPROPERTY('ErrorLogFileName') AS nvarchar(max)))))
END
