展示了如何用WMI的方法获取CUP的使用率
重点在于获取多个CPU或者多核不同的使用率,在现在CPU多核时代这点很重要-Ever since I saw Performance application on Windows 2000, I wondered if there is a way/Windows API to programmatically determine CPU usage for each of the individual CPUs in a multi-processor machine. Though there are many articles for getting the CPU usage, none helped when it came to multi-processor machines.
After some digging in MSDN, I could find WMI (Windows Management and Instrumentation) has a few performance counter classes. I chose to use the Win32_PerfRawData_PerfOS_Processor class in this case as it is supported on Windows 2000 onwards. Platform: |
