How to monitor user traffic on a terminal server?

Question

Analytics

There is a remote terminal server and a complaint from the provider that there is a very large flow of traffic in the morning. On the server, nothing really spins. According to network connection statistics, there really is traffic, and in huge amounts. It is necessary to understand who (from local users) eats traffic, with what (what program) and from what resource.
Prompt software for these purposes.
PS Constant monitoring is not needed, so I'm looking for something free or with a trial period.
