When reviewing IIS logs I see some HTTP 400 responses. To diagnose the problem, I have enabled SVCTrace via the following configuration....
<system.diagnostics>
<sources>
<source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="ServiceModelMessageLoggingListener">
<filter type="" />
</add>
</listeners>
</source>
<source name="System.ServiceModel" switchValue="Warning, ActivityTracing"
propagateActivity="true">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="ServiceModelTraceListener">
<filter type="" />
</add>
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="C:\temp\messages.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">
<filter type="" />
</add>
<add initializeData="C:\temp\tracelog.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
<filter type="" />
</add>
</sharedListeners>
</system.diagnostics>
While IIS continues to receive HTTP 400 responses, these do not show in the SVCTrace file. I assume this is because a HTTP 400 means bad request, and therefore a bad request never made to WCF to be included in a trace file. Is this an incorrect assumption?

I have a WCF service which has logging enabled. But when i do not mention the path for the logs, the svc logs are getting created in "C:\" in this location. Is this the default location for the logs if we are not implicitly mentioned?
<system.diagnostics>

<source name="System.ServiceModel.MessageLogging" switchValue="Verbose,ActivityTracing">

You're starting your path (\Logfilename.svclog) with a backslash (\), meaning "root of the current drive".
If you want the current (bin) directory, remove the backslash.
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).
I'm trying to diagnose a WCF service that is self-hosted in a relatively simple service host process (Service.exe).
I have Service.exe.config configured thus:
<?xml version="1.0" ?>
<configuration>
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="All"
propagateActivity="true">
<listeners>
<add name="traceListener"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData= "c:\temp\Service.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
<system.serviceModel>
<diagnostics>
<messageLogging maxMessagesToLog="1"
maxSizeOfMessageToLog="2147483647"
logEntireMessage="true"
logMessagesAtServiceLevel="true"
logMalformedMessages="true"
logMessagesAtTransportLevel="true">
</messageLogging>
</diagnostics>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0"
sku=".NETFramework,Version=v4.0" />
</startup>
</configuration>
When I look at the resulting svclog file, I see many trace events being logged (I expected only the first message to be logged), and none of the messages being traced show a message body (only headers).
I'm sure I must be missing something simple here, but I don't see it.
UPDATE: When I look at the WCF Config Editor, there are two sections under "Diagnostics": MessageLogging and Tracing. When I click the "EnableMessageLogging" link, my config file gets updated:
<system.diagnostics>
<sources>
<source propagateActivity="true" name="System.ServiceModel" switchValue="All">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add initializeData="c:\temp\MessageBodyTracing.svclog" type="System.Diagnostics.XmlWriterTraceListener"
name="traceListener">

</add>
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="ServiceModelMessageLoggingListener">
<filter type="" />
</add>
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="c:\users\me\documents\visual studio 2010\projects\messagebodytracing\messagebodytracing\app_messages.svclog"

</add>
</sharedListeners>
</system.diagnostics>
I guess the source named System.ServiceModel.MessageLogging is the key - I hadn't seen that in any documentation of message tracing...
Try to add:
<endToEndTracing propagateActivity="true" activityTracing="true" messageFlowTracing="true" />
in your diagnostics node, under messageLogging.
Set LogEntireMessage to true under Diagnostics->MessageLogging in the Service configuration Editor
I'm trying to follow this tutorial on configuring server-side SOAP tracing for my WCF service, as well as the MSDN documentation.
When I run a test, I see Activity 00000000 in Microsoft Service Trace Viewer but the messages tab is empty. C:\temp\Web_tracelog.svclog is being written but C:\temp\Web_messages.svclog is not.
I'm probably missing something simple here, but can't put my finger on it.
The Diagnostics tab of Microsoft Service Configuration Editor says everything is on. Relevant portions of web.config follow.
<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="Verbose,ActivityTracing"
propagateActivity="true">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="ServiceModelTraceListener">
<filter type="" />
</add>
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging" switchValue="Verbose, ActivityTracing">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
<add name="ServiceModelMessageLoggingListener">
<filter type="" />
</add>
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="C:\temp\Web_tracelog.svclog"

name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
<filter type="" />
</add>
<add initializeData="C:\temp\Web_messages.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">
<filter type="" />
</add>
</sharedListeners>
<trace autoflush="true" />
</system.diagnostics>
<system.serviceModel>
<diagnostics>
<messageLogging logEntireMessage="true" logMalformedMessages="true"
logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />
</diagnostics>
</system.serviceModel>
Can't see what's wrong with that config, but here's the config I use that works without a problem if it's of any use:
<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="Verbose,ActivityTracing">
<listeners>
<add name="ServiceModelTraceListener"
initializeData="c:\MyTracelog.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
traceOutputOptions="Timestamp"/>
</listeners>
</source>
</sources>
<trace autoflush="true" />
</system.diagnostics>
<system.serviceModel>
<diagnostics>
<messageLogging logEntireMessage="true" logMalformedMessages="true"
logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />
</diagnostics>
</system.serviceModel>
I am trying to add a WCF RIA service to an existing website.
When I load the page I get a "Load Operation failed for query"
I fire up fiddler2 and get
The resource cannot be found.
<body bgcolor="white">
<span><H1>Server Error in '/' Application.<hr width=100% size=1 color=silver></H1>
<h2> <i>The resource cannot be found.</i> </h2></span>
<font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">
<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
<br><br>
<b> Requested URL: </b>/Services/WCSynthesis-Web-WCSynthDomainService.svc/binary<br><br>
<hr width=100% size=1 color=silver>
So then I try to get the WCF Loggging working
but the Services is empty and so is the
C:\Users\markgreenway\Desktop\My Dropbox\WCSynthesis\WCSynthesis.Web\Web_messages.svclog
File

So I cannot view anything in the Service Trace Viewer
my System.Diagnostics
<system.diagnostics>

I did add a reference to
• Microsoft.RiaServices.Tools
and it started to work (Fiddler Gave me some real information)
