I have done with particluar process memory usage adn CPU time calculation.Here is the code ..

use Win32::Process::Info;
use Win32::Process::List;
$proc= Win32::Process::List->new();
$pi=Win32::Process::Info->new();
%list =$proc->GetProcesses();
open FILE, '>D:\\Automation Team\\Performance\\CPUUsage\\process_detai
+ls1.txt' or die $!;
print FILE "Process Name\t Mem in Bytes \t CPU time \n";
while(1)
        {
        foreach $pid (keys %list)
                {
                #print "$pid : $list{$pid}\n";
                $pname=$list{$pid};
                #print $pname, "\n";
                if (($pname eq q/jqs.exe/))
                        {
                        print FILE "$list{$pid}\t";
                        @process_information=$pi->GetProcInfo($pid);
                        foreach $info (@process_information)
                                {
                                $value_Mem = ${$info}{"WorkingSetSize"
+};
                                print FILE "\t$value_Mem \t";
                                $value_Ker=${$info}{"KernelModeTime"};
                                #print "Kernel Time:=$value_Ker \t";
                                $value_User=${$info}{"UserModeTime"};
                                #print "UserTime:=$value_User \t";
                                $value_CPU=$value_Ker+$value_User;
                                #$value_CPU=$value_CPU/10000000;
                                print FILE "$value_CPU\t";
                                print FILE "\n"
                                }
                         }
                }
        }

I want to calculate CPU usage of this process. Thanks.
