嗨,我正在尝试创建一个自定义性能计数器,用于perfmon.以下代码运行良好,但我有一个问题..
有了这个解决方案,我有一个更新性能计数器值的计时器,但是我不想运行这个可执行文件来获取我需要的数据.这就是我想能够安装计数器作为一次性的事情,然后对数据进行perfmon查询(就像它对所有预安装的计数器一样).
我怎样才能做到这一点?
using System; using System.Diagnostics; using System.Net.NetworkInformation; namespace PerfCounter { class PerfCounter { private const String categoryName = "Custom category"; private const String counterName = "Total bytes received"; private const String categoryHelp = "A category for custom performance counters"; private const String counterHelp = "Total bytes received on network interface"; private const String lanName = "Local Area Connection"; // change this to match your network connection private const int sampleRateInMillis = 1000; private const int numberofSamples = 100; private static NetworkInterface lan = null; private static PerformanceCounter perfCounter; static void Main(string[] args) { setupLAN(); setupCategory(); createCounters(); updatePerfCounters(); } private static void setupCategory() { if (!PerformanceCounterCategory.Exists(categoryName)) { CounterCreationDataCollection counterCreationDataCollection = new CounterCreationDataCollection(); CounterCreationData totalBytesReceived = new CounterCreationData(); totalBytesReceived.CounterType = PerformanceCounterType.NumberOfItems64; totalBytesReceived.CounterName = counterName; counterCreationDataCollection.Add(totalBytesReceived); PerformanceCounterCategory.Create(categoryName,categoryHelp,PerformanceCounterCategoryType.MultiInstance,counterCreationDataCollection); } else Console.WriteLine("Category {0} exists",categoryName); } private static void createCounters() { perfCounter = new PerformanceCounter(categoryName,counterName,false); perfCounter.RawValue = getTotalBytesReceived(); } private static long getTotalBytesReceived() { return lan.GetIPv4Statistics().BytesReceived; } private static void setupLAN() { NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface networkInterface in interfaces) { if (networkInterface.Name.Equals(lanName)) lan = networkInterface; } } private static void updatePerfCounters() { for (int i = 0; i < numberofSamples; i++) { perfCounter.RawValue = getTotalBytesReceived(); Console.WriteLine("perfCounter.RawValue = {0}",perfCounter.RawValue); System.Threading.Thread.Sleep(sampleRateInMillis); } } }
}
