Win32_NetworkConnection - 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_NetworkConnection

Description

The Win32_NetworkClient WMI class represents a network client on a Windows system. Any computer system on the network with a client relationship to the system is a descendent (or member) of this class (for example, a computer running Windows 2000 Workstation or Windows 98 that is part of a Windows 2000 domain).

Example(s)

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

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

my @computers = ("DELL17");
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_NetworkConnection", "WQL",
                  wbemFlagReturnImmediately | wbemFlagForwardOnly);

   foreach my $objItem (in $colItems) {
