query to fetch cpu core usage for windows?

Question

I have to implement a code which populates the cpu core usage per core?

I was able to find information per processor but not for core.

Any WMI query or a command or an API which could fetch the usage of CPU cores.

Thanks in advance.

Win32_PerfFormattedData_PerfOS_Processor or Win32_PerfRawData_PerfOS_Processor class? Namespace ROOT\CIMV2 — JosefZ

Not exactly, will be looking it later, I voted your answer because it gave me somewhat direction, and still looking for precise solution... — Abhijeet Kumar Srivastava

Win32_PerfRawData_PerfOS_Processor

won't be useful because it is uncooked and you have to cook the counters to get something meaningful which requires lots of computation or you can use:

Win32_PerfFormattedData_PerfOS_Processor which is already cooked.

Refer to : WMI counters

select * from Win32_PerfFormattedData_PerfOS_Processor where NOT name = '_Total'

will give you counters per CPU.
