Enterprise SQL Server Performance Summary report missing SQL Server memory metrics an instance -
Description
The Enterprise SQL Server Performance Summary report does not display SQL Server memory metrics for one instance. The other instances display the memory metrics in the report.Running a query against the monitoring host locally using WBEMTEST using a local credential for the "Win32_PerfRawData_MSSQLSERVER_SQLServerAccessMethods" class fails with an "invalid class" message. -
Cause
The SQL Server WMI query failed due to an invalid class message for "Win32_PerfRawData_MSSQLSERVER_SQLServerAccessMethods". This issue occurs in the Windows Management Instrumentation (WMI) extensions to the Windows Driver Model, outside of the Foglight product in situations where the Windows Operating System cannot identify Microsoft's "Win32_PerfRawData_MSSQLSERVER_SQLServerAccessMethods".
