Performance Counter Classes
Performance Counter classes allow scripting and program access to system performance data calculated by existing high-performance providers. For computers running on Windows Vista and later operating systems, different providers supply performance library data through WMI. The WMIPerfClass and WMIPerfInst providers supply classes for both version 1 and version 2 Performance Counters. These providers maintain compatibility with the classes available in earlier operating systems.
Windows Server 2003 and Windows XP: Performance classes derived from Win32_Perf are supplied by the Formatted Performance Data Provider and the Performance Counter Provider.
The following WMI performance data classes represent basic operating system classes. This is not a complete list of classes that you may find on your operating system. For more information, see Performance Libraries and WMI.
