how to check sql server uptime
You can check the uptime of a SQL Server instance using various methods, including SQL queries and the Windows Task Manager. Here are a few ways to do it:
Method 1: Using SQL Query
- Open SQL Server Management Studio (SSMS) or connect to your SQL Server instance using SQLCMD or another SQL client.
- Run the following SQL query:
SELECT create_date AS ‘SQL Server Start Time’ FROM sys.dm_os_sys_info
This query retrieves the start date and time of the SQL Server instance.
- The result will display the SQL Server start time. You can calculate the uptime by subtracting the start time from the current time.
Method 2: Using Task Manager (Windows)
- Press Ctrl + Shift + Esc or Ctrl + Alt + Delete to open the Task Manager in Windows.
- In Task Manager, go to the “Processes” or “Details” tab (depending on your Windows version).
- Look for a process named “sqlservr.exe.” This process represents your SQL Server instance.
- The “Up time” column will show you how long the SQL Server process has been running.
Please note that the Task Manager method provides the uptime of the SQL Server process itself, not the SQL Server service. It’s generally close to the actual SQL Server service uptime but may not be exactly the same.
The SQL query method is more accurate for checking the SQL Server service uptime. However, both methods can be useful depending on your needs.
