为什么频道＆＃34;调试＆＃34;和＆＃34;分析＆＃34;不适用于我的ETW-EventSource实现？

Question

我正在使用Microsoft EventSource Library为我的Web应用程序实现日志记录机制。

该库提供了四个记录事件通道：＆＃34;管理员＆＃34;，＆＃34;操作＆＃34;，＆＃34;调试＆＃34;和＆＃34;分析＆＃34;。管理员和操作渠道工作正常，渠道可见，我能够记录事件。

由于某种原因，调试和分析通道不会出现在事件查看器中，如此屏幕截图所示：

您可以在下面看到我的EventSource实现。此外，我上传了完整的Visual Studio项目，包括控制台测试应用程序here。

有谁知道为什么只有Admin和Operational可用？

public static partial class WebAppEventSourceHandler
{
    [EventSource(Name = "Company-MyProject-WebApp")]
    private sealed class WebAppEventSource : EventSource
    {
        [Event(1, Message = "Instance: [{0}] Exception Type: [{1}] Exception Message: [{2}] Exception Stack Trace: [{3}] Inner Exception Type: [{4}] Inner Exception Message: [{5}] Inner Exception Stack Trace: [{6}]",
            Channel = EventChannel.Admin, Level = EventLevel.Critical, Version = 1)]
        internal void UnhandledException(string instance, string exceptionType, string exceptionMessage, string exceptionStackTrace,
            string innerExceptionType, string innerExceptionMessage, string innerExceptionStackTrace)
        {
            WriteEvent(1, instance, exceptionType, exceptionMessage, exceptionStackTrace, innerExceptionMessage,
                innerExceptionType, innerExceptionMessage, innerExceptionStackTrace);
        }

        [Event(2, Message = "Instance: [{0}] Controller: [{1}] Action: [{2}] Client Message: [{3}] Server Message: [{4}] Parameter: [{5}]",
            Channel = EventChannel.Admin, Level = EventLevel.Error, Version = 1)]
        internal void LogControllerActionError(string instance, string controller, string action,
            string clientSideMessage, string serverSideMessage, string parameter)
        {
            WriteEvent(2, instance, controller, action, clientSideMessage, serverSideMessage, parameter);
        }

        [Event(3, Message = "Instance: [{0}] Controller: [{1}] Action: [{2}] Client Message: [{3}] Server Message: [{4}] Parameter: [{5}]",
            Channel = EventChannel.Operational, Level = EventLevel.Warning, Version = 1)]
        internal void LogControllerActionWarning(string instance, string controller, string action,
            string clientSideMessage, string serverSideMessage, string parameter)
        {
            WriteEvent(3, instance, controller, action, clientSideMessage, serverSideMessage, parameter);
        }

        [Event(4, Message = "Instance: [{0}] Controller: [{1}] Action: [{2}] Message: [{3}] Server Parameter: [{4}]",
            Channel = EventChannel.Operational, Level = EventLevel.Informational, Version = 1)]
        internal void LogControllerActionInfo(string instance, string controller, string action,
            string message, string parameter)
        {
            WriteEvent(4, instance, controller, action, message, parameter);
        }

        [Event(5, Message = "Instance: [{0}] Controller: [{1}] Action: [{2}] Message: [{3}] Server Parameter: [{4}]",
            Channel = EventChannel.Debug, Level = EventLevel.Verbose, Version = 1)]
        internal void LogControllerActionDebug(string instance, string controller, string action,
            string message, string parameter)
        {
            WriteEvent(5, instance, controller, action, message, parameter);
        }

        [Event(6, Message = "Instance: [{0}] Controller: [{1}] Action: [{2}] Message: [{3}] Server Parameter: [{4}]",
            Channel = EventChannel.Analytic, Level = EventLevel.Verbose, Version = 1)]
        internal void LogControllerActionAnalytic(string instance, string controller, string action,
            string message, string parameter)
        {
            WriteEvent(6, instance, controller, action, message, parameter);
        }
    }
}

我使用此cmd代码段来注册eventsource：

C：\ CustomEventSources＆gt; wevtutil.exe im EventSourceExample.Company-MyProject-WebApp.etwManifest.man /rf:"C:\CustomEventSources\EventSourceExample.Company-MyProject-WebApp.etwManifest.dll" / MF：＆＃34; C：\ CustomEventSources \ EventSourceExample.Company-MyProject的-WebApp.etwManifest.dll＆＃34;

Answer 1

按default the Analytic and Debug are disabled：

  

默认情况下禁用分析和调试日志。启用后，他们   可以快速填写大量条目。出于这个原因，你   可能想要将它们打开一段指定的时间来收集   一些故障排除数据，然后再将其关闭。您可以   使用Windows界面或a执行此过程   命令行。

您必须manually show them in the Eventviewer options：

  

  
1. 启动事件查看器。
  
2. 点击View菜单。如果选择Show Analytic and Debug Logs，则分析和调试日志已可见。没有进一步的行动   需要。如果未选择Show Analytic and Debug Logs，请选择Show   Analytic and Debug Logs使这些日志可见。
