Configure Sql Server Error Logs
accepted There is a setting if you right click on "SQL Server Logs" and select "Configure". You can tell it how many log files you want to keep. Once it reaches that number it will start removing the old ones. share|improve this answer answered Oct 29 '14 at 14:43 Kenneth Fisher 16.8k53171 add a comment| up vote 8 down vote Restart SQL Server 7 times. You will see you still have only 7 ERRORLOG* files (depending on version). This is the current log file and the 6 most recent log files. Note: You may need to change 7 to something else, in the event you changed the number of error logs SQL Server keeps. The max, I believe, is 99. But no matter what your current setting is, it will eventually recycle and purge old files. I tested this and, if you uncheck the box that says: ☐ Limit the number of error log files before they are recycled ...which implies (at least to me) keep all log files, it will still keep only the current error log file plus 6 backups. If you've changed the registry key that @RLF pointed out, the registry key setting overrides (as if you hadn't unchecked the box), but you're still going to be limited to some number of backup error log files between 6 and 99. So the short answer is: yes, in all cases, SQL Server will eventually get around to deleting old error log files. share|improve this

Randal in SQL Server Questions Answered RSS EMAIL Tweet Comments 0 Question: Some of the SQL Server instances I manage routinely have extremely large (multiple gigabytes) error logs because they are rebooted so infrequently. Trying to open an error log that large is really problematic. Is http://sqlmag.com/blog/how-prevent-enormous-sql-server-error-log-files there a way that the error logs can be made smaller? Answer: I completely sympathize with you. Very often when dealing with client systems we encounter similar problems. Thankfully there is an easy solution. (See also, "Choosing Default Sizes for Your Data and Log Files" and "Why is a Rolled-Back Transaction Causing My Differential Backup to be Large?"). The number of error logs is set to 6 by default, and a new one is created each time the server restarts. Old ones are renamed when a new one is created and the oldest is deleted. As you’ve noticed, this can lead to extremely large error log files that are very cumbersome to work with. There is a registry setting ‘NumErrorLogs’ that controls the number of error log files to keep in the LOG directory. This can easily be changed through Management Studio. In Object Explorer for the instance, navigate to Management then SQL Server Logs. Right-click and select Configure as sho
Facebook Twitter LinkedIn YouTube GitHub Forgotten Maintenance - Cycling the SQL Server Error Log September 30, 2015Jeremiah Peschka20 comments Most of us get caught up in fragmentation, finding the slowest queries, and looking at new features. We https://www.brentozar.com/archive/2015/09/forgotten-maintenance-cycling-the-sql-server-error-log/ forget the little things that make managing a SQL Server easier - like cylcing http://www.sqlideas.com/2015/07/purge-sql-server-logs-and-agent-error.html the SQL Server error logs. What's the Error Log? The SQL Server error log is a file that is full of messages generated by SQL Server. By default this tells you when log backups occurred, other informational events, and even contains pieces and parts of stack dumps. In short, it's a treasure trove of sql server information. When SQL Server is in trouble, it's nice to have this available as a source of information during troubleshooting. Unfortunately, if the SQL Server error log gets huge, it can take a long time to read the error log - it's just a file, after all, and the GUI has to read that file into memory. Keep the SQL Server Error Log Under Control It's possible sql server error to cycle the SQL Server error log. Cycling the error log starts a new file, and there are only two times when this happens. When SQL Server is restarted. When you execute sp_cycle_errorlog Change everything! When SQL Server cycles the error log, the current log file is closed and a new one is opened. By default, these files are in your SQL Server executables directory in the MSSQL\LOG folder. Admittedly, you don't really need to know where these are unless you want to see how much room they take up. SQL Server keeps up to 6 error log files around by default. You can easily change this. Open up your copy of SSMS and: Expand the "Management" folder. Right click on "SQL Server Logs" Select "Configure" Check the box "Limit the number of error log files before they are recycled" Pick some value to put in the "Maximum number of error log failes" box Click "OK" It's just that easy! Admittedly, you have to do this on every SQL Server that you have, so you might just want to click the "Script" button so you can push the script to multiple SQL Servers.

8:00 AM Purge SQL Server Logs and Agent Error Logs One day when I checked the disk space on C:\ drive where I have installed SQL Server, then space is full and free space is not available. I have checked all the folders and files on C:\ drive, but the problem was different. The size of SQL Server error log file goes very high and this cause to disk was full. I have reviewed and the current error log files cause for the same. I have tried to remove it to make free space on disk, but I could not delete as it was used by SQL Server. Then I have applied one script to detach the current error logs and create a new file in the error logs. Generally, when the new error files generated when SQL Service restart. The script looks as follows, here I have given a sample example as how to detach last active ERROR logs from SQL Server, so after that we can remove those previous error log files. We have a look for the file shots of SQL Server error log files and Agent error log files as well before the script run. -- Using MSDB database to run the command USE MSDB GO -- Removing SQL Server error logs EXEC SP_CYCLE_ERRORLOG GO -- Removing SQL Server Agent error logs EXEC SP_CYCLE_AGENT_ERRORLOG GO Let us go, through the screen below which will show the new files created for the same. What do you think, have you applied any script or schedule to create new error log files and remove previous error log files?
