测量特定应用程序的带宽

我需要测量我制作的应用程序的带宽。假设这个应用程序被调用 myapp.exe .

我做了一个图书馆叫 BandwidthMonitor (BM)从内部调用 . 定期电话 BM.Measure() BandwidthMeasurement .

BM

public class BandwidthMonitor
{
    PerformanceCounter bandwidthCounter;
    PerformanceCounter dataReceivedCounter;
    PerformanceCounter dataSentCounter;

    List<float> byetsSent = new List<float>();
    List<float> byetsReceived = new List<float>();
    List<float> byetsUtilization = new List<float>();

    float bandwidth;
    int ticks = 0;

    static string categoryName = ".NET CLR Networking 4.0.0.0";

    public BandwidthMonitor()
    {
        try
        {

            bandwidthCounter = new PerformanceCounter();
            bandwidthCounter.CategoryName = categoryName;
            bandwidthCounter.CounterName = "Current Bandwidth";
            bandwidthCounter.InstanceName = instance;
            bandwidthCounter.ReadOnly = true;

            dataReceivedCounter = new PerformanceCounter();
            dataReceivedCounter.CategoryName = categoryName;
            dataReceivedCounter.CounterName = "Bytes Received/sec";
            dataReceivedCounter.InstanceName = instance;
            dataReceivedCounter.ReadOnly = true;

            dataSentCounter = new PerformanceCounter();
            dataSentCounter.CategoryName = categoryName;
            dataSentCounter.CounterName = "Bytes Sent/sec";
            dataSentCounter.InstanceName = instance;
            dataSentCounter.ReadOnly = true;

            Console.WriteLine("Bandwidth monitor ready.");

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }
    }

    public BandwidthMeasurement Measure()
    {
        var measurement = new BandwidthMeasurement();
        ticks++;

        try
        {
            var bytesSent = dataSentCounter.RawValue;
            var bytesReceived = dataReceivedCounter.RawValue;

            measurement.BytesSent = bytesSent;
            measurement.ByesReceived = bytesReceived;

            double utilization = (8 * (bytesSent + bytesReceived)) / (bandwidth * ticks) * 100;

            measurement.Utilization = utilization;

        }
        catch (Exception ex)
        {

            Console.WriteLine(ex);
        }


        return measurement;
    }

    //https://stackoverflow.com/a/27418721/596841
    private static string GetInstanceName()
    {
        string returnvalue = "not found";
        //Checks bandwidth usage for CUPC.exe..Change it with your application Name
        string applicationName = "myapp";
        PerformanceCounterCategory[] Array = PerformanceCounterCategory.GetCategories();
        for (int i = 0; i < Array.Length; i++)
        {
            if (Array[i].CategoryName.Contains(categoryName))
                foreach (var item in Array[i].GetInstanceNames())
                {
                    Console.WriteLine(item);
                    if (item.ToLower().Contains(applicationName.ToString().ToLower()))
                        returnvalue = item;
                }

        }
        return returnvalue;
    }
}

因为某种原因, GetInstanceName() 总是返回 not found . 我不明白为什么。

我试过:

• 设置 categoryName .NET CLR Networking
• 经过 myapp processId 致 并查找类别。
• BM公司 实例化以确保 是完全加载和操作第一(我认为这是毫无意义的,但我不知道还有什么可以尝试。。。抓住救命稻草。

PerformanceCounterCategory category = new PerformanceCounterCategory(".NET CLR Networking  4.0.0.0"); // and without the 4.0.0.0
var instanceNames = category.GetInstanceNames().Where(i => i.Contains(string.Format("p{0}", processId)));

if (instanceNames.Count() == 0) throw new Exception("Instance name not found");

传递processId也找不到实例名称。

我一直有例外:

我做错什么了?
