After we get this value, we keep it for the next run (the refresh time is usually 1.5 seconds) we then decrease the new value from the old value and divide I guess that I can get this information with the methods that you pointed me to. Background My journey began when I had to write a Task Manager look alike that also had some netstat features. The [Process>% Processor Time] counter is related to (nb of logical CPUs) * [Processor>% Processor Time].

C# Performancecounter Cpu Usage

It is not related to [Processor>% User Time] !!! (if you understand the way the CPU works, it is merely illogical to even say it would be related). private PerformanceCounter theMemCounter = new PerformanceCounter("Process", "Working Set", Process.GetCurrentProcess().ProcessName); where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

For instance, you can look at %idle (or %halted): http://software.intel.com/en-us/articles/measuring-the-halted-state/ Or the average unhalted frequency: http://software.intel.com/en-us/articles/measuring-the-average-unhalted-frequency/ Or the IPC (instructions per clocktick) where the max is 4 or 5 instructions per So the calculation of a CPU usage must be something like this "(CurrentUsedMilliseconds - OldUsedMilliseconds) / 15".

Process returns the full file name but the Process Perf API expects just the file stem, so the extension is stripped by the code. Did 17 U.S. I know of no easy way to get how much CPU a process is using from perfmon. thank you.

Instead, I start the PCM - run some test - stop PCM - look at collected counter values (usually collected per second). My big thanks go to PInvoke for their contribution to the translated API availability which helped me a lot.

They simply check Task Manager (or Process Explorer) just to find out that the value does not match the SCOM alert. I tested this example on different computers with different hardware (i7, i5, Core2) and software configurations (Windows 7 SP1 with all updates, Windows 2008 R2 SP1 with all updates) and got Word for unproportional punishment? So we can easily calculate the amount of milliseconds making one percent of CPU usage 0.01 * 1500 = 15 milliseconds.

I set up a counter with the following settings: Process -> % Processor Time -> all instances Here is an example. Is it bad practice to use GET method as login username/password for administrators? Consider making a small donation to show your support. I also tried to shut down as much as possible so that only 7zip and performance monitor was running.

In the end I created a small reusable class that provides a more performant version: public class ProcessCpuCounter { public static PerformanceCounter GetPerfCounterForProcessId(int processId, string processCounterName = "% Processor Time") { I don't know if the API version is always good, it requires much more work than the managed one, but if you are after your own "Task Manager" you should definitely What are the benefits of an oral exam? But to calculate the utilization, I would also need the maximum possible number of instructions that can be executed so that I can output "actual"/"maximum".

One way would be to change the way process instance names are generated (see http://support.microsoft.com/kb/281884) but this has the potential of affecting other apps using the perfmon api. I tried it and it's a good method as long as you use only a few (1-3) PerformanceCounters because it consumes a lot of CPU which got me to a usage
