Win32_PerfRawData_PerfOS_Memory - WMI sample in VBScript

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.

The Win32_PerfRawData_PerfOS_Memory WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


Win32_PerfRawData_PerfOS_Memory

Description

The Win32_PerfFormattedData_PerfOS_Memory "cooked" data performance counter class represents calculated counters that describe the behavior of physical and virtual memory on the computer. Physical memory is the amount of random access memory on the computer. Virtual memory consists of the space in physical memory and on disk. Many of the memory counters monitor paging, which is the movement of pages of code and data between disk and physical memory. Excessive paging, a symptom of a memory shortage, can cause delays which interfere with all system processes. This class is the Memory object for the PerfOs performance provider. 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_Memory. The original data source is the PerfOS performance library. This class was added for Windows XP.
