The System.Management namespace provides access to a wide range of management information and management event collections related to system, device, and application setting checkpoints based on the Windows Management Instrumentation (WMI) architecture. Applications and services can use classes derived from ManagementObjectSearcher and managementquery to query for administrative information of interest (for example, how much free space is left on the disk, what is the current
VBScript code to get CPU usage through WMI
Niang, search the keyword "WMI CPU usage", get all Is "Python uses WMI monitor system-CPU Usage", do not look, certainly again collect.
Python is powerful, but invoking WMI is more "authentic" than using VBS.

Get CPU brand
Recent Intel and AMD processors have an extend CPUID function call, that returns the name of the processor. In earlier cpu models you had to use the version and feature information function of CPUID to look up names in a string list of your own.
The function GetBrandString shows how to access the brand string, provided the CPUID instuction is availa
In Linux, if you want to monitor the operation of a process, such as viewing its CPU usage and memory usage, you need to read some system information from the system's/proc directory. Then the analysis results, especially in the embedded application This function is very important. The code in this article is obtained from the source analysis of the top command and has been partially modified and passed in fc6+gcc4.1 debugging. From this project I als
