Framework Diagnostics

All components of the framework log to the TraceSource “DurableTask”. Listeners can be attached to this trace source to get the framework traces.

The framework ships with a TraceListener that logs to the Console and Debug streams. The class name of the listener is DurableTask.Tracing.OrchestrationConsoleTraceListener.

Here is a snippet of an app.config file that shows how to load the console trace listener:

  <system.diagnostics>
    <trace autoflush="true"/>
    <sources>
      <source name="DurableTask"
              switchName="traceSwitch"
              switchType="System.Diagnostics.SourceSwitch" >
        <listeners>
          <clear/>
          <add name="configConsoleListener" 
            type=" DurableTask.Tracing.OrchestrationConsoleTraceListener, DurableTask"
               traceOutputOptions="DateTime" />
        </listeners>
      </source>
    </sources>
    <switches>
      <add name="traceSwitch" value="Verbose" />
    </switches>
  </system.diagnostics>
