Receiver REST adapter output

I have a scenario where I am sending data to target system using rest adapter(Rest adapter at receiver end).

The target system demands some http-headers along with data. I have added those headers under HTTP Headers tab and those are working fine.

However, I am interested in seeing what HTTP request message is being sent by the adapter. I am interested in getting the complete payload in which I can see the HTTP request/response parameters as well as the xml payload that is being sent to the target system.

Is there anyway to obtain the information that I am looking for?
