1.如何启用跟踪 

如下为启用WCF的跟踪信息

http://msdn.microsoft.com/zh-cn/library/ee517292.aspx

<configuration>

  <system.serviceModel>

    <diagnostics>

      <messageLogging maxMessagesToLog="30000" logEntireMessage="true" logMessagesAtServiceLevel="true" logMalformedMessages="true" logMessagesAtTransportLevel="true"> </messageLogging>

    </diagnostics>

  </system.serviceModel>

  <system.diagnostics>

    <sources>

      <!-- This section turns on digest logging, note that for this to work correctly, you need to add the following to machine.config: <system.serviceModel> <machineSettings enableLoggingKnownPii="true" /> </system.serviceModel> Search for 'DigestTrace' in the trace viewer to view the digest logs. -->

      <source name="System.IdentityModel" switchValue="Verbose" logKnownPii="true">

        <listeners>

          <add name="xml" />

        </listeners>

      </source>

      <!-- Log all messages in the 'Messages' tab of SvcTraceViewer. -->

      <source name="System.ServiceModel.MessageLogging">

        <listeners>

          <add name="xml" />

        </listeners>

      </source>

      <!-- ActivityTracing and propogateActivity are used to flesh out the 'Activities' tab in SvcTraceViewer to aid debugging. -->

      <source name="System.ServiceModel" switchValue="Error, ActivityTracing" propagateActivity="true">

        <listeners>

          <add name="xml" />

        </listeners>

      </source>

      <!-- This records Microsoft.IdentityModel generated traces, including exceptions thrown from the framework. -->

      <source name="Microsoft.IdentityModel" switchValue="Warning">

        <listeners>

          <add name="xml" />

        </listeners>

      </source>

    </sources>

    <sharedListeners>

      <add name="xml" type="System.Diagnostics.XmlWriterTraceListener" initializeData="trace.e2e" />

    </sharedListeners>

    <trace autoflush="true" />

  </system.diagnostics>

</configuration>

以下为事务的跟踪信息

<system.diagnostics>
  <sources>
   <source name="System.Transactions" switchValue="Information">
   <listeners>
    <add name="tx" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "tx.log" />
   </listeners>
  </source>
 </sources>
</system.diagnostics>
