    Question Unanswered: Find Last Restart of SQL Server


    How can I tell when my SQL Server instance was last started? In this tip we look at various methods of how to get the start time for a SQL Server instance.

    Here are a few different ways that you can tell when SQL Server was last started.
    Method 1: sys.dm_os_sys_info

    This DMV, sys.dm_os_sys_info, contains a column that holds the startup time for SQL Server. You can run the following command to find the start time.
    SELECT sqlserver_start_time FROM sys.dm_os_sys_info


    Method 2: SQL Server Error Log

    If you open the current SQL Server error log in SSMS under Management > SQL Server Logs and scroll to the bottom of the error log you can see when the server was started. Note the highlighted text below "SQL Server is starting". You will want to look for this to make sure the error log was not cycled and give you a false impression of the start time.

    sql server error log start up time

    Here is an example of a cycled error log and note the highlighted text. If you see this you will need to look at a previous error log until you find the log that contains the information in the image above.

    Note: if you are running the Express edition of SQL Server you cannot read the error logs directly from SSMS, but you can use xp_readerrorlog or navigate to the folder where the log files are stored and use a text editor to read the SQL Server error log files.

    sp_helpdb tempdb
    this will tell you tempdb creation time (which is essentially when you sql server was started)
    You can also check error logs which contain startup information.
