Win32_Thread perl 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_Thread WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_Thread WMI class represents a thread of execution. While a process must have one thread of execution, the process can create other threads to execute tasks in parallel. Threads share the process environment, thus multiple threads under the same process use less memory than the same number of processes.

Sample Code

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_Thread", "WQL",
                  wbemFlagReturnImmediately | wbemFlagForwardOnly);
