parse through and interpret the data you collected. One of these areas where errors and other sql server event log informational data is stored is the SQL Server error log. The problem with the error log file is that there is so much data collected sql server 2014 error log location it is sometimes hard to determine where the real errors lie. By default all backups and integrity checks are logged in the error log. In addition, if you are auditing logins these messages are also stored in the error log, so https://msdn.microsoft.com/en-us/library/ms187109.aspx this further compounds the problem. It is great to have all of this data, but trying to find your problems can become quite a chore. So how can you find the errors much easier? SolutionWith SQL Server 2005 Microsoft has made this a bit easier to set filters, but this is still pretty cumbersome and does not really provide you all of the data you need. The best approach as with many things is to build your own data parser and that https://www.mssqltips.com/sqlservertip/1307/simple-way-to-find-errors-in-sql-server-error-log/ is what we did using Windows Scripting and VBScript. Here is a simple view of the Error Log as it normally displays: Here is a simple view of the Error Log after only the errors have been parsed out. As you can see this new version is much easier to read and also only shows you the errors instead of all that additional informational data that is stored in the error logs. In addition, it shows you all of the error lines at the particular time the error occurred, so you do not need to go back to the error log to get the additional error lines. Setting it up Below is a VBScript that allows you to parse out the error messages. It is not the most elegant piece of code, but it does work. The script takes two arguments: logType - 2000 (SQL 2000) or 2005 (SQL 2005) fileName - name and path of the file that you want to parse This could be called from a command line such as the following. ParseLog.vbs "2005" "C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG.5" Before you can use this, you need to save the following code into a new file called "ParseLog.vbs". Once you have done this you are ready to roll. This code will read the file that you specify and will create a secondary file using the same name and appending a "2" at the end of the file name.

In this tip we look at different ways a DBA can identify the location of the SQL Server Error Log file used by an instance of SQL Server. Solution In this tip we will take http://dba.stackexchange.com/questions/31298/safe-way-to-truncate-sql-server-error-log a look at three different ways you identify which SQL Server Error Log file is used by an instance of SQL Server. 1. Reading the SQL Server Error Logs2. Using SQL Server Configuration Manager3. Using sql server Windows Application Event Viewer Let's take a look at each of the above options in detail. Identify SQL Server Error Log File used by SQL Server Database Engine by Reading SQL Server Error Logs The SQL Server Error Log is a great place to find information about what is happening on your database server. You can execute the below TSQL command which uses the XP_READERRORLOG extended stored procedure to read the SQL sql server error Server Error Log to find the location of SQL Server Error Log file used by the instance of SQL Server. USE master GO xp_readerrorlog 0, 1, N'Logging SQL Server messages in file', NULL, NULL, N'asc' GO XP_READERRRORLOG The parameters you can use with XP_READERRRORLOG are mentioned below for your reference: 1. Value of error log file you want to read: 0 = current, 1 = Archive #1, 2 = Archive #2, 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. Search from start time 6. Search to end time 7. Sort order for results: N'asc' = ascending, N'desc' = descending By default, there are six archived SQL Server Error Logs along with the ERRORLOG which is currently used. However, it is a Best Practice to increase the number of SQL Server Error Logs from the default value of six. Hence I recommend you read this tip Increase the Number of SQL Server Error Logs.

Basically, it'll create a new error log file that SQL Server will be hitting. Then the archived error log(s) can be treated accordingly (delete/move with caution). This will not technically "truncate" the log, it'll just roll it over and you can handle the old logs as you so please, like any other file system file. When you do this, you should see a new log file with an entry that resembles the following: The error log has been reinitialized. See the previous log for older entries.

No. Read the question again and take a closer look at the picture. –ivanmp Jan 5 '13 at 9:00 @JohnDaCosta please reread the question. I believe you are mistaken. –Thomas Stringer Jan 5 '13 at 12:56 1 It's worth noting that sp_cycle_errorlog only recycles ONE log file. But because there are 7 files, if you really want to purge them and save space (as I did) you will need to run the
