I want to calculate CPU Usage of aprticular process.I have calculated Memory USage and CPU Time 

use Win32::Process::Info;
my  $pi = Win32::Process::Info->new();
my @process_information  = $pi->GetProcInfo(1333);
while(1){
foreach  $info (@process_information) {
                  foreach my $key (keys %{$info})
                {
        if ($key eq "WorkingSetSize")
                {
            $value_Mem = ${$info}{$key}/1024;
        print "$key:=>$value_Mem \t"
        }
                if ($key eq "KernelModeTime")
                {
                $value_Ker=${$info}{$key};
                print "$key:=$value_Ker \t"
                }
        if ($key eq "UserModeTime")
                {
                $value_User=${$info}{$key};
                print "$key:=$value_User \t"
                }
          }
                $value_CPU=$value_Ker+$value_User;
                $value_CPU=$value_CPU/10000000;
                print "CPU Time :=$value_CPU\t";
                print "\n"
 }
}

In the code I have passed the process ID.Since the process id changes I want to pass the process name.Is this possible
