of the issues I have is that the SQL xp_readerrorlog sql 2014 Server Error Log is quite large and it is not always easy to view the sql server logs location contents with the Log File Viewer. In a previous tip "Simple way to find errors in SQL Server error log" you discussed a method

of searching the error log using VBScript. Are there any other easy ways to search and find errors in the error log files? SolutionSQL Server 2005 offers an undocumented system stored procedure sp_readerrorlog. This SP allows you to read the contents of the SQL Server error log files

directly from a query window and also allows you to search for certain keywords when reading the error file. This is not new to SQL Server 2005, but this tip discusses how this works for SQL Server 2005. This is a sample of the stored procedure for SQL Server 2005. You will see that when this gets called it calls an extended stored procedure xp_readerrorlog. CREATE PROC [sys].[sp_readerrorlog]( Dev centers Samples Retired content We’re sorry.

You can compare it to the event viewer in Windows, but than only http://www.lucasnotes.com/2012/10/querying-sql-server-error-log.html for SQL Server. This error log contains a lot of potentially useful information when you're investigating an issue. The physical location of the logfiles is "C:\Program Files\Microsoft SQL Server\MSSQL12.[InstanceName]\MSSQL\Log". This can also be different if you changed the path in the SQL Server setup (for example, the path on my machine is: "C:\Program Files\Microsoft SQL Server 2014\MSSQL12.[InstanceName]\MSSQL\Log"). In that directory you'll find sql server a number of ERRORLOG.[Number] files. There is a file for every archive, which depends on your SQL Server configuration. You can open the files with notepad, or any other text-editor you like. But you can also access these archives from SQL Server Management Studio (SSMS). SQL Server Logs If you connect the object explorer in your SSMS, you can navigate to Management -> SQL Server Logs. There you see the number of configured log files (default is 7 sql server error log files: 6 archives + current log file): You can double-click a log file to open it. In the pop-up window you see the contents of the log, a number of checkboxes on the left to add more archives to the current view, and a button called "Filter…" that you can use to filter the current view: But unfortunately the filter in the Log File Viewer isn't always as easy to use. For example, you can't (at least as far as I know) filter on 2 strings. So how are you going to look for any events that contains "Backup" or "Restore"? That's not possible with this filter. xp_readerrorlog If you would rather use T-SQL to find things in the SQL Server Error Log, that's also possible. There's an extended procedure called xp_readerrorlog you can use for that, or you can use sp_readerrorlog (which is a stored procedure that used xp_readerrorlog). If you use sp_readerrorlog or xp_readerrorlog, you can also apply filters. You can use a number of parameters to filter the output, but you can only do so on 1 singe log file: EXEC xp_readerrorlog 0, --ArchiveID (First error log = 0) 1, --Log type (SQL Server = 1, SQL Agent = 2) N'Backup', --Filter ProcessInfo N'Sandbox', --Filter Text '20150826 00:00:00', --DateFrom '20150828 10:32:00', --DateTill 'ASC' --Sort order By altering the filter-parameters (or leave them empty), you while back, I wrote a blog post about reading SQL Server error log using Microsoft Log Parser. That blog post can be found here. There are many ways in which you can query the SQL Server error log. One of them is using the sys.sp_readerrorlog stored procedure. This stored procedure can be located in the master database. It accepts 4 input parameters: @p1 - integer: This parameter is to specify which error log to read. SQL Server error log would rollover. By default, SQL Server error log would keep a file for the current log and maximum 6 of archived logs (this setting can be changed easily), ERRORLOG, ERRORLOG.1, ERRORLOG.2, ERRORLOG.3, ERRORLOG.4, ERRORLOG5 and ERRORLOG6. ERRORLOG is where SQL Server stores the current error log, ERRORLOG.1 is where SQL Server stores the most recent archived, etc. If we put 0 or null on this parameter, we are querying the current error log (ERRORLOG). 1 would refer to ERRORLOG.1. The same concept would apply to SQL Server Agent error log. @p2 - integer: This parameter is to specify if we want to query the SQL Server Error Log or the SQL Server Agent Error Log. If we enter 1 or null, we are querying the SQL Server Error Log. However, if we enter 2, then we are querying the SQL Server Agent Error Log. @p3 - varchar(255): We can specify word or phrase that we are looking within the text/message on the SQL Server error log or SQL Server Agent error log. @p4 - varchar(255): We can specify word or phrase that we are looking within the text/message on the SQL Server error log or SQL Server Agent error log. If we enter a word or phrase on @p3 parameter and enter another word or phrase on @p4 parameter, the stored procedure should return error log entries that contain both words/phrases (AND operator). If we leave @p3 blank but enter a word or phrase on @p4, the stored procedure would not filter the error log. It will ignore the @p4 parameter filter. Some Usage Examples The following would return all entries on the current SQL Server error log (ERRORLOG): EXEC sp_readerrorlog or: EXEC sp_readerrorlog 0 or: EXEC sp_readerrorlog NULL, NULL, NULL, NULL The following would return all entries on the current SQL Server Agent error log (SQLAGENT.OUT): EXEC sp_readerrorlog 0, 2 The following would return entry from SQL Server error log when the SQL Server was starting the msdb database (in this case it was part of the server start up): EXEC sp_readerrorlog 0, 1, 'starting', 'msdb' This would returns: Wait, There's more… If we look at the sp_readerrorlog stored procedure code closely, it is actually calling the xp_readererrorlog extended stored procedure. The xp_readerrorlog actually accepts more input pa
