Win32_Process - WMI sample in Perl

The foundations for Manageability in Windows 2019/2016/2012/2008 and Windows 10/7/XP 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_Process WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


Win32_Process

Description

The Win32_Process WMI class represents a sequence of events on a Windows operating system. A descendent or member of this class is a sequence that consists of an interaction of one or more processors or interpreters, some executable code, and a set of inputs, for example, a client application running on a Windows system.

Example(s)

  use strict;
use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;

my @computers = ("\localhost");
foreach my $computer (@computers) {
   print "\n";
   print "==========================================\n";
   print "Computer: $computer\n";
   print "==========================================\n";

   my $objWMIService = Win32::OLE->GetObject("winmgmts:\\\\$computer\\root\\CIMV2") or die "WMI connection failed.\n";
   my $colItems = $objWMIService->ExecQuery("SELECT * FROM Win32_Process", "WQL",
                  wbemFlagReturnImmediately | wbemFlagForwardOnly);
