Ask Kathleen

How-To Q&A: I have set up my Web service for tracing, but I can’t find my trace logs.

A reader sets up a Web service for tracing, but can't find the trace logs, despite the lack of any error message.

A reader asks: I have set up my Web service for tracing, and I receive no error. But I can’t find my trace logs. My configuration file is:

         <source name="System.ServiceModel"
                       switchValue="Verbose, ActivityTracing"
               <add name="MyServiceListener" />
         <add name="MyServiceListener"
             initializeData="c:\logs\ServerTraces.svclog"  />

Neither the logs directory nor the service log file exist after I run my application. Can you see what is wrong with my configuration?

Kathleen Answers: The problem is actually not in the configuration. The trace will not create the directory, and will not give an error that the trace file cannot be written to disk. This results in a silent failure. Create the directory and rerun your application and you should find your trace logs.
