Win32_PerfRawData_PerfOS_Objects jscript sample code

The foundations for Manageability in Windows is 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. The Win32_PerfRawData_PerfOS_Objects WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_PerfFormattedData_PerfOS_Objects "cooked" data performance counter class represents calculated counts of the objects contained by the operating system such as events, mutexes, processes, sections, semaphores, and threads. This class is shown as the Objects 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_Objects. The original data source is the PerfOS performance library. This class was added for Windows XP.

Sample Code

var wbemFlagReturnImmediately = 0x10;
var wbemFlagForwardOnly = 0x20;

var arrComputers = new Array("\localhost");
for (i = 0; i < arrComputers.length; i++) {
   WScript.Echo();
   WScript.Echo("==========================================");
   WScript.Echo("Computer: " + arrComputers[i]);
   WScript.Echo("==========================================");

   var objWMIService = GetObject("winmgmts:\\\\" + arrComputers[i] + "\\root\\CIMV2");
   var colItems = objWMIService.ExecQuery("SELECT * FROM Win32_PerfRawData_PerfOS_Objects", "WQL",
                                          wbemFlagReturnImmediately | wbemFlagForwardOnly);

   var enumItems = new Enumerator(colItems);
   for (; !enumItems.atEnd(); enumItems.moveNext()) {
      var objItem = enumItems.item();

      WScript.Echo("Caption: " + objItem.Caption);
      WScript.Echo("Description: " + objItem.Description);
      WScript.Echo("Events: " + objItem.Events);
      WScript.Echo("Frequency_Object: " + objItem.Frequency_Object);
      WScript.Echo("Frequency_PerfTime: " + objItem.Frequency_PerfTime);
      WScript.Echo("Frequency_Sys100NS: " + objItem.Frequency_Sys100NS);
      WScript.Echo("Mutexes: " + objItem.Mutexes);
