Debugging WCF - Traces and Message Logs

  • Artikel

There has been enough posts on this topic. But this topic cannot be over emphasized. The best way to debug any WCF issue is to get a complete Message log and trace. We write tons of information to the trace that there is very little (if any) issues that traces cannot solve. Below is a config to generate Message logs and Traces in the Verbose level. The config will create a file e2eTraceTest.e2e in the directory where the config lives.

 <configuration>

          <system.serviceModel>

                  <diagnostics>

                          <messageLogging maxMessagesToLog="30000" 

                                  logEntireMessage="true" 

                                  logMessagesAtServiceLevel="true" 

                                  logMalformedMessages="true" 

                                  logMessagesAtTransportLevel="true">

                          </messageLogging>

                  </diagnostics>

          </system.serviceModel>

          <system.diagnostics>

                  <sources>

                          <source name="System.ServiceModel" 

                                  switchValue="Verbose, ActivityTracing" 

                                  propagateActivity="true" >

                                  <listeners>

                                          <add name="xml" />

                                  </listeners>

                          </source>

                          <source name="System.ServiceModel.MessageLogging" 

                                  switchValue="Verbose">

                                  <listeners>

                                          <add name="xml" />

                                  </listeners>

                          </source>

                  </sources>

                  <sharedListeners>

                          <add name="xml" 

                               type="System.Diagnostics.XmlWriterTraceListener" 

                               initializeData="e2eTraceTest.e2e" />

                  </sharedListeners>

                  <trace autoflush="true" />

          </system.diagnostics>

  </configuration>
