Keep your login as an active login to the server. If you have logged into the server to start the trace make sure you do not log off or the trace will be stopped. To set up this monitoring, there is no need to restart SQL Server Services.

SQL Server 2000 uses the same event ID for both, making it impossible to determine if the event signifies success or failure without looking at the event details. Successful logins for SQL Server 20 will have an event ID of 18454 and failed logins will have an event ID of 18456. If you look in this event log, you will be looking for events with a source of MSSQLSERVER or MSSQL$. To view the Application event log, expand System Tools, and then Event Viewer. Likewise, to search the current error log and only return failed logins we can use the following command:ĮXEC sp_readerrorlog 0, 1, ‘Login failed’Īlternatively, with log management software, we could obtain these details from the Application event log for the operating system.
For instance, to see the contents of the 3rd log we would pass a parameter of 2 as shown below: To dump the results of the error log to a recordset, use:Īn integer parameter can be given to the extended stored procedure to read the older SQL server log.

Let us now look at each of the methods in detail.
There are different methods available to audit the logins in SQL server. SQL Server permits the auditing of both login successes and failures. However, to perform an investigation on an event that happened in the past, we will require these details from a particular time frame. To obtain the login details of a particular database in real-time is an easy task. Let us today discuss the possible steps to audit failed logins in SQL server. Auditing failed logins in the SQL server at times is important to analyze the events that happened in the past.Īs a part of our Server Management Services, we help our customers to perform complex SQL related tasks regularly.
