Win32_PerfRawData_PerfOS_System - WMI sample in Perl

The foundations for Manageability in Windows 7/2008/Vista/XP/2000 and Millennium Edition/'98 are Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself.

On this site, you can find many WMI samples.


Win32_PerfRawData_PerfOS_System

Description

The Win32_PerfFormattedData_PerfOS_System "cooked" data performance counter class represents calculated counters that apply to more than one instance of a component processors on the computer. This class is shown as the System object in System Monitor. The WMI source of its data is the high-performance Cooked Counter Provider. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfOS_System. The original data source is the PerfOS performance library. This class was added for Windows XP.
