Monitoring Windows CPU Utililization for process

[omid1979]

hi all ,
I want to monitor CPU Utilization for one windows Process ( for example firefox) , I know I can using perf_counter[\Process(_Total)\% Processor Time] parameter to monitor total cpu utilization ,
But when I want to monitor for special process I usge perf_counter[\Process(firefox)\% Processor Time] it show me more than 100 ( for example 120% ,

How Can I monitor CPU Utilization for each process in percentage ?

this is similar to what I am trying. I want to monitor a process CPU usage(i.e. firefox) , just like the value returned in Task Manager. The closest one I have come across is "perf_counter[\Process(firefox)\% Processor Time]" / number of cores (i.e. 8). This value is quite close to the value I saw in Task manager. But I'm still not sure...
