How to enable tracing for WCF ajax enabled services? - wcf

How to enable tracing for WCF ajax enabled services? I have the following code:
<system.diagnostics>
<sources>
<source name="System.ServiceModel.MessageLogging">
<listeners>
<add name="messages"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData="c:\logs\messages.svclog" />
</listeners>
</source>
</sources>
but it doesn't work.
thanks in advance.

Try like this:
<sources>
<source name="System.ServiceModel"
switchValue="Information, ActivityTracing"
propagateActivity="true">
<listeners>
<add name="sdt"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData="c:\logs\messages.svclog" />
</listeners>
</source>
</sources>

How to trace a specific endpoint on source System.Net

I'm trying to setup tracing for a specific endpoint in my WCF application.
I've tried with Filters on the "messageLogging" element in servicemodel, but it doesn't seem to apply on the sources System.Net and System.Net.Sockets.
I can't run tracing on all endpoints in production since it will add up to much storage. Doesnt anyone know how to filter the output to the listener to only include traffic on one specific endpoint?
My web.config looks like this:
<system.diagnostics>
<trace autoflush="true"/>
<sources>
<source name="System.Net">
<listeners>
<add name="TraceFile"/>
</listeners>
</source>
<source name="System.Net.Sockets">
<listeners>
<add name="TraceFile"/>
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="C:\Temp\TracingSystemNet.svclog" type="System.Diagnostics.XmlWriterTraceListener" name="TraceFile" />
</sharedListeners>
<switches>
<add name="System.Net" value="Verbose" />
<add name="System.Net.Sockets" value="Verbose" />
</switches>
</system.diagnostics>

WCF Tracing log message is set to false, but there is still a trace output being generated

I have the following configuration
<system.serviceModel>
<diagnostics>
<messageLogging logEntireMessage="false" logKnownPii="false" logMalformedMessages="false" logMessagesAtServiceLevel="false" logMessagesAtTransportLevel="false" maxMessagesToLog="250000000" maxSizeOfMessageToLog="262144000">
<filters>
<clear />
</filters>
</messageLogging>
<endToEndTracing propagateActivity="true" activityTracing="true" messageFlowTracing="true" />
</diagnostics>
<system.diagnostics>
<sources>
<source propagateActivity="true" name="System.ServiceModel" switchValue="Off, ActivityTracing">
<listeners>
<add name="RollingDateXmlWriterTraceListener" />
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging" switchValue="Off">
<listeners>
<add name="RollingDateXmlWriterTraceListener" />
</listeners>
</source>
</sources>
<sharedListeners>
<!--<add name="xml" type="System.Diagnostics.XmlWriterTraceListener" initializeData="C:\Temp\Logs\MainService.svclog" />-->
<add name="RollingDateXmlWriterTraceListener" type="XXX.Common.Listeners.RollingDateXmlWriterTraceListener, XXX.Common" traceOutputOptions="None" initializeData="C:\Temp\Logs\MainService.{yyyyMMdd}.svclog" />
</sharedListeners>
<trace autoflush="true" />
I have set false to all of the logMessage attributes, but i still get the svclog file. Do I miss something?

WCF Service Log - create a new file when exceed a file size limit or create it for every day

My application is using WCF, And I am creating a service log file on server. It is working correctly, It is writing same svclog file and it is increasing in size.
What would I have to do to create a new svclog file when it reaches a fixed file size like I want it to be 50MB, or it creates a new svclog file for each day.
Currently, The source and listeners have been defined in the web.config file as follows:
<system.diagnostics>
<sources>
<source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
<listeners>
<add name="ServiceModelTraceListener" />
</listeners>
</source>
<source name="System.ServiceModel" switchValue="Verbose,ActivityTracing">
<listeners>
<add name="ServiceModelTraceListener" />
</listeners>
</source>
<source name="System.Runtime.Serialization" switchValue="Verbose,ActivityTracing">
<listeners>
<add name="ServiceModelTraceListener" />
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="C:\ServiceLogs\app_tracelog.svclog" type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="ServiceModelTraceListener" traceOutputOptions="Timestamp" />
</sharedListeners>
</system.diagnostics>
How can I do this?
You should create a custom trace listener.
There is a perfect sample from MS for this ! This example can not fit exactly with your needs, but it is easy to understand and so to change.

Difference between a listener with no <filter> and one with <filter type=""/>

I've seen many examples where a <source> node has been setup in <System.Diagnostics> in configuration files for tracing like so:
<source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
<listeners>
<clear/>
<add name="SharedListener">
<filter type="" />
</add>
</listeners>
</source>
Is there any difference between that and removing the <filter> node:
<source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
<listeners>
<clear/>
<add name="SharedListener"/>
</listeners>
</source>
and if so, what? It's not a big deal except the extra lines of code and Resharper's solution-wide analysis complaining about an empty type attribute.
There is no difference, except fewer lines of XML.

WCF: How do I trace message bodies?

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">
<filter type="" />
</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"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">
<filter type="" />
</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
