Win32_PerfRawData_TermService_TerminalServices 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_TermService_TerminalServices WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


Description

The Win32_PerfRawData_TermService_TerminalServices raw data performance counter class represents raw data terminal services summary information. This class is shown as the Terminal Services object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the TermService performance library. The corresponding formatted data class is Win32_PerfFormattedData_TermService_TerminalServices. This class was added for Windows 2000.

Sample Code

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

   foreach my $objItem (in $colItems) {
