WCF Tracing: Can we view Request and Response body?

I have a WCF service and i want to view the actual request & response (the content) from the service. So i enabled WCF Tracing with Verbose. After adding tracing, the service started logging into .svclog file, when i open the file into viewer

i do not see actual content of the message in any of the logged messages.

For example, in logviewer, under description column, i see "Received a message over a channel", but it only logs Message Header. Is there anyway to see entire body without changing the code.(WCF service hosted in IIS and but we don't have access to code)

                     name="System.ServiceModel"                      switchValue="Verbose"                     propagateActivity="true">                              name="traceListener"                     type="System.Diagnostics.XmlWriterTraceListener"                     initializeData= "C:\logs\Traces.svclog" />
