Qualifiers Specific to WMI Performance Classes

Raw performance counter classes, derived from Win32_PerfRawData, contain uncalculated values that serve as input for Win32_PerfFormattedData classes, as well as System Monitor calculations.

Performance counter qualifiers specify information about the performance object and the counters for that object. Performance objects map to WMI performance counter classes and performance counters are represented by the properties of the WMI class.
