Win32_PerfRawData_PerfProc_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_PerfRawData_PerfProc_Thread WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


Description

The Win32_PerfFormattedData_PerfProc_Thread "cooked" data performance counter class represents calculated counters that measure aspects of thread behavior. A thread is the basic object that executes instructions on a processor. All running processes have at least one thread. This class is shown as the Thread 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_PerfProc_Thread. The original data source is the PerfProc performance library. This class was added for Windows XP.

Sample Code

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

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

my @computers = ("\localhost");

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