How to check traffic and connected devices?

Question

Recently, I setup my Pi 3 to work as Wi-Fi access point through the Tor network. Is there any way to check what devices are connected and how much traffic is sent through the Pi by individual devices? Some sort of admin area like routers have?

You can use the ipfm command line tool, a very good tool for your requirements.

For more information, see man(8) ipfm.

Sample output:
