需要使用CounterDelta32 PerformanceCounter的示例

这是一个对我有用的例子。

class Program
{
    const string CategoryName = "____Test Category";
    const string CounterName = "Clear State Operations";

    static void Main(string[] args)
    {
        if (PerformanceCounterCategory.Exists(CategoryName))
            PerformanceCounterCategory.Delete(CategoryName);

        var counterDataCollection = new CounterCreationDataCollection();

        var clearStateCounterData = new CounterCreationData()
        {
            CounterName = CounterName,
            CounterHelp = "The number of times the service state has been cleared since the last performance iteration",
            CounterType = PerformanceCounterType.CounterDelta32
        };
        counterDataCollection.Add(clearStateCounterData);

        PerformanceCounterCategory.Create(CategoryName, "Test Perf Counters", PerformanceCounterCategoryType.SingleInstance, counterDataCollection);

        var counter = new PerformanceCounter(CategoryName, CounterName, false);

        for (int i = 0; i < 5000; i++)
        {
            var sw = Stopwatch.StartNew();
            Thread.Sleep(10300);
            sw.Stop();

            counter.Increment();
        }

        Console.Read();
    }
}

这不足以创建计数器…根据文档,您需要创建一个 PerformanceCounterCategory 并创建 PerformanceCounter . 查看msdn中的示例: http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecounter.aspx

创建计数器后(使用CounterCreationData和Create in PerformanceCounterCategory),然后创建计数器的实例(使用PerformanceCounter),需要初始化计数器值以在性能监视器中启动该实例。

另外,确保您正在以读写模式创建计数器(通过向readonly参数传递false)。

您可以尝试设置rawvalue=rawvalue或rawvalue=0来启动它并查看它是否出现。
