WCF Server side logging message send back progress - wcf

Question

I am getting timeouts on the client side and I am not sure if the issue is the package size or the network.
On the server side is there a way of logging the progress of the message being sent to the client?
Or at least the size of the package being sent on the transport layer?
Note: I've looked into WCF Logging options before posting question, but couldn't find anything regarding the message size, especially if binding is not Http so there is no specific header with the Content-Length.
Thanks

You can add to your config file these lines:
<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>
More information you can find on MSDN page.

This was the best thing I did manage to achieve, couldn't find anything out of the box:
public class MessageSizeBehaviorAttribute : Attribute, IContractBehavior
{
public void Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
{
}
public void ApplyDispatchBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, DispatchRuntime dispatchRuntime)
{
dispatchRuntime.MessageInspectors.Add(new MessageSizeInspector());
}
public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
}
public void AddBindingParameters(ContractDescription contractDescription, ServiceEndpoint endpoint,
BindingParameterCollection bindingParameters)
{
}
}
public class MessageSizeInspector : IDispatchMessageInspector
{
public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
{
return request;
}
public void BeforeSendReply(ref Message reply, object correlationState)
{
try
{
if (reply.IsFault || reply.IsEmpty) return;
var buffer = reply.CreateBufferedCopy(int.MaxValue);
reply = buffer.CreateMessage();
var messageBodyReader = buffer.CreateMessage().GetReaderAtBodyContents();
var messageBody = messageBodyReader.ReadOuterXml();
LogMessageSize(messageBody);
}
catch (Exception e)
{
Debug.WriteLine(e);
}
}
private void LogMessageSize(string messageBody)
{
double messageSize = Encoding.UTF8.GetByteCount(messageBody);
Debug.WriteLine("Message size in MBytes {0}", messageSize / 1024 / 1024);
}
}
