C++ Get Cpu Usage Windows


Vladimir February 3, 2015 at 7:38 am Thanks! its in c.. I'd be interested in seeing what you come up with. I have looked at TestPDH_TaskManager.au3 and it seems easier for me to understand. Check This Out

Thanks for your reply! I made sure I have the exact CpuUsage.cpp, CpuUsage.h, and PerfCounters.h. I am passing an array to the GetUsage method as follows: public short GetUsage(String[] procName) { String[] myProcs = procName; if (!Monitor.TryEnter(_syncLock)) { return _cpuUsage; } if (!EnoughTimePassed) { Monitor.Exit(_syncLock); return it always shows 100%.However the original, unmodified sample project i downloaded here is dead right on the CPU load.

I wonder if this has to do with you using pdh instead of the kernel32.dll that I was kind of trying to go after. or only for NT/2000/XP: const SystemBasicInformation = 0; SystemPerformanceInformation = 2; SystemTimeInformation = 3; type TPDWord = ^DWORD; TSystem_Basic_Information = packed record dwUnknown1: DWORD; I used the following method to set the thread affinity to Low public static void setCurrentProgAffinity(String proc) { foreach (Process myCurrentProcess in Process.GetProcessesByName(proc)) { myCurrentProcess.PriorityClass = System.Diagnostics.ProcessPriorityClass.Idle; } } Deekshit February I might want to monitor 1 process or 3 at anytime.

However, most are process specific monitoring. We just need to compare the time spent by a process to the time spent by all processes on the computer, since the last time we made such a measurement. Different is CPU usage for process.

Thank again for your code! C++ Get Cpu Usage Linux The discrepancy is possibly due to the fact I don't grab the percentage as a float, but instead as an integer..As far as PDH.DLL it is just an API interface to However, CPU usage can be retrieved by using performance counters. The critical section run count enables the code to be called in a multi-threaded environment without problems.

Over time, they should average out to the same, though.

The Process class reports times in TimeSpans, not FILETIME, so our class is modified accordingly. 1: using System;using System.Collections.Generic; 2: using System.Linq; 3: using System.Text; 4: using System.Runtime.InteropServices; 5: using ComTypes

At least have one call the other... PdhOpenQuery(NULL, 1, &m_hQuery); PdhAddCounter(m_hQuery, "\\Process(FineSpeak)\\% Processor Time", 0, &m_hIVRCounter); PdhCollectQueryData(m_hQuery); PdhGetFormattedCounterValue(m_hIVRCounter, PDH_FMT_LONG, NULL, &stFormattedValue); // stFormattedValue.longValue = CPU usage.

or is there a leak? -Deekshit Ben Post authorFebruary 5, 2009 at 12:21 pm Deekshit, the demo program deliberately uses a lot of the processor in order to demo the functionality http://chatflow.net/cpu-usage/cpu-usage-100-windows-10.html With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the Thanks for sharing!!!

the task manager uses native api calls for the process times, I know it calls NtQuerySystemInformation (passing SystemProcessesAndThreads enum) which would contain the processes kernel/user time, I would assume the PdhGetFormattedCounterValue How many CPUs are there?

any help thanks nisar September 30, 2011 at 3:54 pm Hi, the conversion in C# SubtractTimes (((UInt64)(a.dwHighDateTime << 32)) | (UInt64)a.dwLowDateTime) is incorrect. Pdhaddcounter Updated 2/4/2009: I changed the implementation of these classes from the original: Instead of a critical section, InterlockedIncrement/Decrement is used. The correct conversion is (((UInt64)f.dwHighDateTime) << 32) | (UInt32)f.dwLowDateTime.

It seems to work very well and is perfect for for what I need but it looks like this procedure only will run on the local machine. Do you have any suggestions? This is so weird. Getprocesstimes Cpu Usage Can you please help Ben?

Each process spends some time in kernel mode and some time in user mode. Sign in here. January 14th, 2004, 06:57 AM Mick Quote: Originally posted by ham7446 Hi Mick. navigate here Ascend4nt has an excellent script.
