我想显示我的多线程应用程序的CPU使用率(在多核处理器上工作).我想收到任务经理附近的数字.但我得到的数字超过100%.甚至超过500%.是的,我知道,对于类别"进程"的计数器"%Processor Time",我需要分为Environment.ProcessorCount或"NumberOfLogicalProcessors"(我的配置相同).此操作后结果为500%.我在具有不同硬件(i7,i5,Core2)和软件配置(带有所有更新的Windows 7 SP1,带有所有更新的Windows 2008 R2 SP1)的不同计算机上测试了此示例,并遇到了同样的问题.

public static class SystemInfo
{
    private static Process _thisProc;
    private static bool HasData = false;
    private static PerformanceCounter _processTimeCounter;

    private static void Init()
    {
        if (HasData)
            return;

        if (CheckForPerformanceCounterCategoryExist("Process"))
        {
            _processTimeCounter = new PerformanceCounter();
            _processTimeCounter.CategoryName = "Process";
            _processTimeCounter.CounterName = "% Processor Time";
            _processTimeCounter.InstanceName = FindInstanceName("Process");
            _processTimeCounter.NextValue();
        }

        MaximumCpuUsageForCurrentProcess = 0;
        HasData = true;
    }

    private static bool CheckForPerformanceCounterCategoryExist(string categoryName)
    {
        return PerformanceCounterCategory.Exists(categoryName);
    } …

我想使用.NET/Process性能计数器在网页上显示一些内存统计信息(工作集,GC等).不幸的是,如果该服务器上有多个应用程序池,则使用索引(#1,#2等)对它们进行区分,但我不知道如何将进程ID(我有)与该#xx索引进行匹配.是否有编程方式(来自ASP.NET网页)？

我正在使用这个类作为一类测试的基类,这些测试启动一个进程并给它一些输入,并在给它更多输入之前等待它变为空闲.

public abstract class TestProcessLaunchingBase
{
    protected PerformanceCounter PerfCounter { get; set; }

    protected void WaitForProcessIdle()
    {
        while (true)
        {
            float oldValue = PerfCounter.NextValue();

            Thread.Sleep(1000);

            float nextValue = PerfCounter.NextValue();

            if (nextValue == 0)
                break;
        }
    }

    protected void FindSpawnedProcessPerfCounter(int processId)
    {
        PerformanceCounterCategory cat = new PerformanceCounterCategory("Process");
        string[] instances = cat.GetInstanceNames();
        foreach (string instance in instances)
        {
            using (PerformanceCounter cnt = new PerformanceCounter("Process", "ID Process", instance, true))
            {
                int val = (int)cnt.RawValue;
                if (val == processId)
                {
                    PerfCounter = new PerformanceCounter("Process", …
