I have written a program in vbscript for getting system usage information, but while tried the same in perl failed to get the data. 

' run as cscript hello.vbs
Dim strMessage
strMessage = "Hello world in VB Script!"
WScript.Echo strMessage

strComputer = "."
Set objWMIService = GetObject("winmgmts:" & _
         "{impersonationLevel=impersonate}!\\" & _
         strComputer & "\root\cimv2")
Set colSettings = objWMIService.ExecQuery _
   ("Select * from Win32_OperatingSystem")
For Each objOperatingSystem in colSettings 
   Wscript.Echo "Total Physical Memory: " & objOperatingSystem.TotalVi
+sibleMemorySize
   Wscript.Echo "Free Physical Memory: " & objOperatingSystem.FreePhys
+icalMemory 
   Wscript.Echo "Total Virtual Memory Size: " & objOperatingSystem.Tot
+alVirtualMemorySize 
   Wscript.Echo "Free Virtual Memory Size: " &  objOperatingSystem.Fre
+eVirtualMemory
Next


'also want to get percentage of CPU, Memory, VirtualMemory used

Here adding my perl script. 

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

my $NameSpace = "root/cimv2";
my $Machine = shift @ARGV || ".";

$Machine =~ s/^[\\\/]+//;

print $Machine."\n";

my $WMIServices = Win32::OLE->GetObject( "winmgmts:{impersonationLevel
+ = impersonate}!//$Machine/$NameSpace" ) || die;

# get TotalVisibleMemorySize, FreePhysicalMemory,  TotalVirtualMemoryS
+ize, FreeVirtualMemory
print "Win32_OperatingSystem: ";
my $memOS = $WMIServices->InstancesOf(Win32_OperatingSystem);
printf "%s %ld %ld %ld %ld",$memOS->{Name}, $memOS->{TotalVisibleMemor
+ySize},
          $memOS->{FreePhysicalMemory}, $memOS->{TotalVirtualMemorySiz
+e},
        $memOS->{FreeVirtualMemory};
