Win32_DiskQuota 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_DiskQuota WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

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

   foreach my $objItem (in $colItems) {
      print "DiskSpaceUsed: $objItem->{DiskSpaceUsed}\n";
      print "Limit: $objItem->{Limit}\n";
      print "QuotaVolume: $objItem->{QuotaVolume}\n";
      print "Status: $objItem->{Status}\n";
      print "User: $objItem->{User}\n";
      print "WarningLimit: $objItem->{WarningLimit}\n";
      print "\n";
