In this article I would like to demonstrate how we can increase the number of logs in SQL Server for the engine. The SQL Server error log contains events and errors related to SQL Server engine and services. You can use this error log to troubleshoot problems related to SQL Server. The default value for the maximum number of log files is 6. However we can increase that. The maximum number of logs can be up to 99.

Let us now see how we can increase the number of SQL Server logs via SSMS:
Step 1: Connect to the SQL Server where you want to perform this
Step 2: Expand the management folder
Step 3: Right Click on SQL Server Logs
Step 4: Click on Configure
Step 5: When you click on configure the ‘Configure SQL Server Error Logs’  box opens. Change the Maximum number of error logs to the desired number.
Step 6: Click on OK.
We can also run the below query to attain the same:

USE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE',
N'Software\Microsoft\MSSQLServer\MSSQLServer',
N'NumErrorLogs',
REG_DWORD, 14
GO
