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;

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：

启动事件查看器。

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。

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