如何监控特定应用程序的网络带宽使用情况？

Question

我正在尝试学习如何监控特定应用程序的网络带宽使用情况。我正在查看IPv4InterfaceStatistics，但似乎这只能监视网卡的性能。
我想监视特定应用程序，以查看每秒消耗了多少带宽。
是否有人知道如何实现这一点的示例？

@DeepakMishra 我认为他想以编程方式解决这个问题，因为它涉及到C#和堆栈，而不是服务器故障，但我可能错了。 - Magic-Mouse

是的，我想以编程方式解决这个问题。 - Manish Jain

Answer 2

这是一个使用 PerformanceCounter 进行了修改的版本：

var processFileName = Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);
var bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = VersioningHelper.MakeVersionSafeName(processFileName, ResourceScope.Machine, ResourceScope.AppDomain);
bytesReceivedPerformanceCounter.ReadOnly = true;

Console.WriteLine("Bytes received: {0}", bytesReceivedPerformanceCounter.RawValue);

Answer 3

如果您熟悉OSI模型http://en.wikipedia.org/wiki/OSI_model，您会发现您试图与第3层交互，而应该与第7层交互。

在您使用的任何类中，您可以测量发送的字节数，特别是如果您正在传输单个字节（这是因为我不知道您的代码是什么样子），您应该能够计算一段时间内的字节数，除以秒数，然后您就有了结果。
