ETW调试配置

Question

我试图使用ETW记录服务中的错误/异常。

事件源非常基本：

public class Logger : EventSource
{
    public static readonly Logger Instance = new Logger();

    // Use default trace listener so only profiler sees this data
    // it will not be part of Tako

    private Logger()
    {
        // Do nothing, but make the constuct private so static singleton use is enforced
    }

    [Event(EventId.StoreValueException, Level = EventLevel.Critical)]
    public void CriticalException(Exception ex, int eventId)
    {
        WriteEvent(eventId, ex);
    }

    [Event(EventId.StoreValueException, Level = EventLevel.Error)]
    public void Exception(Exception ex, int eventId)
    {
        WriteEvent(eventId, ex);
    }

    [Event(EventId.StoreValueException, Level = EventLevel.Warning)]
    internal void Warning(string p, params object[] paramList)
    {
        WriteEvent(EventId.StoreValueLog, String.Format(p, paramList));
    }

    [Event(EventId.StoreValueException, Level = EventLevel.Informational)]
    public void Info(string p, params object[] paramList)
    {
        WriteEvent(EventId.StoreValueLog, String.Format(p, paramList));
    }

    [Event(EventId.StoreValueException, Level = EventLevel.Verbose)]
    public void Verbose(string p, params object[] paramList)
    {
        WriteEvent(EventId.StoreValueLog, String.Format(p, paramList));
    }
}

现在，我试图使用该源登录到一个文件：

<system.diagnostics>
<sources>
  <source name="MyNameSpace" switchValue="All" >
    <listeners>
      <add name="ErrorLoggingListener">
        <filter type="" />
      </add>
    </listeners>
  </source>
  <source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
    <listeners>
      <add name="ServiceModelMessageLoggingListener">
        <filter type="" />
      </add>
    </listeners>
  </source>
</sources>
<sharedListeners>
  <add initializeData="C:\ap\app\test\logs\fullweb.log"
      type="System.Diagnostics.TextWriterTraceListener" name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">
    <filter type="" />
  </add>
  <add initializeData="C:\ap\app\test\logs\errors.log"
      type="System.Diagnostics.TextWriterTraceListener" name="ErrorLoggingListener" traceOutputOptions="Timestamp">
    <filter type="" />
  </add>
</sharedListeners>
</system.diagnostics>
<system.serviceModel>
<diagnostics performanceCounters="All" >
  <messageLogging logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="false" />
</diagnostics>
</system.serviceModel>

因此，system.serviceModel日志记录工作，但我的事件源日志不能。我觉得我必须设置一些东西告诉侦听器，以记录一切。SwitchValue=All似乎没有做这个把戏
