    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

      It's still not clear to me from this thread nor your previous what you are actually trying to achieve, but you might take a look at DBD::WMI.
