How is CPU Core utilization calculated for Windows servers?
CPU Core Utilization :
The same way in CPU Utilization, we execute the below query and from the output we execute another query to get the details of CPU Core details.
Select * from Win32_PerfRawData_PerfOS_Processor where Name!='_Total'
Select * from Win32_PerfRawData_PerfOS_Processor where Name!='&object.name&'
Then do the same calculation like CPU Utilization.
