I suppose that would only be possible to a certain limit. You can find out e.g. using " Activity: All Events and Netflow - Top Destination Ports "
report as to how much of traffic was utilized for RDP, but to get actual and true picture of netflow, you cannot use MARS, as it does not report the conversations, rather it uses netflow to detect any anomolies ONLY from logging the traffic and detecting sources and destination IP addresses. It doesn't really coorelate the data received through netflow.
