I'm Trying go GET CPU values using WMI classes but with no lucky.

1. With the class "Win32_PerfFormattedData_PerfOS_Processor", I'm always getting the same values they don't change...
2. With the WMI class "Win32_PerfRawData_PerfOS_Processor", the value of "PercentProcessorTime" is equal to "PercentProcessorTime", something is wrong...

#!/usr/bin/perl -w use strict; use warnings;

use Win32::OLE;
use Data::Dumper;

my $class = "Win32_PerfFormattedData_PerfOS_Processor";
my $key = 'Name';

my @properties = qw(PercentIdleTime PercentProcessorTime PercentPrivilegedTimePercentUserTime PercentInterruptTime);
my $wmi = Win32::OLE->GetObject("winmgmts://./root/cimv2")
    or die "Failed getobject\n";

my $list, my $v;

$list = $wmi->InstancesOf("$class")
    or die "Failed getobject\n";
my $hash;
foreach $v (in $list) {        
    $hash->{$v->{$key}}->{$_}  = $v->{$_} for @properties;
}

print Dumper $hash;

#-------------------
# Using Otehr class    
$class = 'Win32_PerfRawData_PerfOS_Processor';

$wmi = Win32::OLE->GetObject("winmgmts://./root/cimv2")
    or die "Failed getobject\n";

$list = $wmi->InstancesOf("$class")
    or die "Failed getobject\n";
foreach $v (in $list) {        
    $hash->{$v->{$key}}->{$_}  = $v->{$_} for @properties;
}

print Dumper $hash;
