Where do Azure wcf service Trace.WriteLine requests go? - wcf

Question

I have looked at a lot of different Azure and Wcf service examples. I have configured a trace listener and much trace information is appearing in the associated log file; however, I don't see the results of my Trace.WriteLine requests. I do see my Trace.WriteLine requests in the Azure debugger output panel.. Where is the output of these requests persisted?
From my Web.config
<system.diagnostics>
<sources>
<source propagateActivity="false" name="System.ServiceModel"
switchValue="Verbose,ActivityTracing">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="AzureLocalStorage">
<filter type="" />
</add>
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging" switchValue="Information">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="AzureLocalStorage">
<filter type="" />
</add>
</listeners>
</source>
</sources>
<sharedListeners>
<add type="WCFServiceWebRole1.AzureLocalStorageTraceListener, WCFServiceWebRole1"
name="AzureLocalStorage">
<filter type="" />
</add>
</sharedListeners>
<trace autoflush="true" />
From my AzureLocalStorageTraceListener.cs
public class AzureLocalStorageTraceListener : XmlWriterTraceListener
{
public AzureLocalStorageTraceListener()
: base(Path.Combine(AzureLocalStorageTraceListener.GetLogDirectory().Path, "WCFServiceWebRole1.svclog"))
{
}
public static DirectoryConfiguration GetLogDirectory()
{
DirectoryConfiguration directory = new DirectoryConfiguration();
directory.Container = "wad-tracefiles";
directory.DirectoryQuotaInMB = 10;
directory.Path = RoleEnvironment.GetLocalResource("WCFServiceWebRole1.svclog").RootPath;
return directory;
}
}

The AzureLocalStorageTraceListener you created simply logs to a *.svclog file. If you want to output logs to the emulator there are a few things you should take care of:
Add the DevelopmentFabricTraceListener to your shared listeners (this will also work for the 1.7 SDK)
<add type="Microsoft.ServiceHosting.Tools.DevelopmentFabric.Runtime.DevelopmentFabricTraceListener, Microsoft.ServiceHosting.Tools.DevelopmentFabric.Runtime, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Emulator">
<filter type="" />
</add>
Make sure the switch value is correct (you could try the value All to get started)
Change the logging level in the emulator (by right clicking the icon at the top right of the screen).
