“SQL Server Install Date” query does not work in some countries!
In France, I amended the query as follows:
SELECT @@SERVERNAME AS [Server_Name], create_date AS [SQL_Server_Install_Date], name AS [Principal_Name]
FROM sys.server_principals WITH (NOLOCK)
WHERE name IN ( /*English*/ N’NT AUTHORITY\SYSTEM’
, /*French*/ N’AUTORITE NT\Système’)
OR name IN ( /*English*/ N’NT AUTHORITY\NETWORK SERVICE’
, /*French*/ N’AUTORITE NT\SERVICE RÉSEAU’)
OPTION (RECOMPILE);

Thank you very much for your contributions

In reply to Praveen. I have periodically received reports of this issue on relatively large machines (in terms of core counts). The sys.dm_os_ring_buffers DMV is not fully documented or supported by Microsoft, so I don't know if this issue will ever be fixed.

Hi Glenn,

I am running this SQL on a machine with 4 NUMA nodes and 96 logical cores.

This seems to return incorrect results for SQLProcessUtilization with values > 100.

Is there any work-around for this to determine the SQLProcessUtilization accurately?

Thanks.
