请求的性能计数器不是自定义计数器，必须初始化为ReadOnly。“在RouteTable.Routes.MapHubs（）;

问题描述 投票：17回答：5

我在AspNet MVC 4应用程序中使用SignalR 1.1.2版本和Windsor Castle。我的问题是，自从我转移到较新的SignalR版本后，此错误消息显示出来。

"The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly."

在线

    RouteTable.Routes.MapHubs();

这是RegisterHubs类

public static class RegisterHubs
{
    public static void Start()
    {
        var signalrDependencyContainer = new WindsorContainer().Install(new HubsInstaller());
        var signalrDependency = new SignalrDependencyResolver(signalrDependencyContainer.Kernel);
        GlobalHost.DependencyResolver = signalrDependency;
        RouteTable.Routes.MapHubs();
    }
}

我已经尝试了一些我在互联网上找到的东西，比如：

lodctr /R
cd C:\Windows\Inf\.NETFramework
lodctr corperfmonsymbols.ini

但我仍然收到相同的错误消息。有任何想法吗？

我正在使用dotnet framework 4.5。

这是堆栈跟踪

at System.Diagnostics.PerformanceCounter.InitializeImpl()

谢谢！

因此，根据您提供的信息，很明显，这些是在SignalR尝试创建性能计数器时抛出的第一次机会异常，但没有权利使用运行该进程的标识来执行此操作。您可以安全地忽略这些异常，但显然您无法获得性能计数器数据。

如果要创建性能计数器，则需要确保应用程序的标识在运行时属于Performance Counter Users组。要么你需要使用Microsoft ASP.NET SignalR Utilities NuGet package中提供的实用程序应用程序，它允许你在带外创建计数器。只需安装包并运行命令：

signalr ipc

Drew Marsh's response，也解决了我的问题。以下是描述如何运行signalr命令的其他详细信息：

使用软件包管理器安装SignalR Utils：

  1. 在VS中：工具 - >库包管理器 - >包管理器控制台
  2. 从命令行键入： PM> Install-Package Microsoft.AspNet.SignalR.Utils
  3. 以管理员身份运行IDE，运行： PM> signalr ipc

运行性能计数器安装命令（signalr ipc）需要管理员权限 - 运行时不执行此操作会导致此错误：

错误：System.Security.SecurityException：不允许请求的注册表访问。在System.Diagnostics.PerformanceCounterLib.RegisterCategory的System.Diagnostics.PerformanceCounterLib.CreateRegistryEntry（String categoryName，PerformanceCounterCategoryType categoryType，CounterCreationDataCollec tion creationData，Boolean＆iniRegistered）中的Microsoft.Win32.RegistryKey.OpenSubKey（String name，Boolean writable）（String category Name， PerformanceCounterCategoryType categoryType，String categoryHelp，Counter CreationDataCollection creationData）at System.Diagnostics.PerformanceCounterCategory.Create（String categoryName，String categoryHelp，PerformanceCounterCategoryType categoryType，CounterCreationDataCollection counterData）at Microsoft.AspNet.SignalR.Utils.PerformanceCounterInstaller.InstallCounters（）

请注意，如果您按照上面提到的（正确）建议并调用'signalr ipc'来安装SignalR的自定义计数器，那么在运行调试器时，您的应用程序可能会莫名其妙地完全停止工作。问题是CLR在初始化时如何处理CultureInfo的错误。问题至少存在于SignalR 2.2.0中。这里将讨论完整的解释和几个解决方法：https://github.com/SignalR/SignalR/issues/3414

解决了这个问题。在我的测试或生产服务器中，我没有安装在其中的Visual Studio这样的IDE。所以我坚持同样的错误。最后我简单地做了以下步骤：

请按照安装VS的服务器中的以下步骤操作

  • 在VS中：工具 - > NuGet包管理器 - >包管理器控制台从命令行键入：
  • PM> Install-Package Microsoft.AspNet.SignalR.Utils
  • 转到包 - > Microsoft.AspNet.SignalR.Utils.2.2.3 - >工具
  • 复制signalr.exe

请按照测试或生产服务器中的以下步骤操作

  • 将signalr.exe粘贴到bin - > debug文件夹下并复制路径
  • 在管理员模式下打开命令提示符并将目录更改为复制的路径
  • 输入并运行命令signalr.exe ipc

成功运行上面的命令后，我启动了它运行良好的应用程序。如果他们在测试环境中需要它，我刚刚为其他人发布了这个。

这是一个无法以管理员权限运行的开发人员的解决方案。创建下面的类并将其添加到DependencyResolver，如下所示：

// Stop exception being thrown when trying to access performance counters
var dummyPerformanceCounterManager = new DummyPerformanceCounterManager();
GlobalHost.DependencyResolver.Register(
    typeof(IPerformanceCounterManager), 
    () =>dummyPerformanceCounterManager);

这是替换PerformanceCounterManager的类

public class DummyPerformanceCounterManager : IPerformanceCounterManager
{
  private readonly static PropertyInfo[] _counterProperties = GetCounterPropertyInfo();
  private readonly static IPerformanceCounter _noOpCounter = new NoOpPerformanceCounter();

  public DummyPerformanceCounterManager()
  {
    foreach (var property in _counterProperties)
    {
      property.SetValue(this, new NoOpPerformanceCounter(), null);
    }
  }

  public void Initialize(string instanceName, CancellationToken hostShutdownToken)
  {
  }

  public IPerformanceCounter LoadCounter(string categoryName, string counterName, string instanceName, bool isReadOnly)
  {
    return _noOpCounter;
  }

  internal static PropertyInfo[] GetCounterPropertyInfo()
  {
    return typeof(DummyPerformanceCounterManager)
        .GetProperties()
        .Where(p => p.PropertyType == typeof(IPerformanceCounter))
        .ToArray();
  }
