As far as I know i need to instantiate the Performance Counter before I use it, like: 
# pseudo algorithm 

my $inst = new PerformanceCounter('CPU');
while(true){
  $sample = $inst->get_next_sample();
  print $sample->{'total'};
  print $sample->{'idle'};
  print $sample->{'system'};
  print $sample->{'user'};
}

But i don't know how to do it using WMI. I think I'm forced to use other method, that doesn't use WMI. Any tips?

Tks
