With the 2019.10.0 release we have added a new option that will allow you to display only public traffic for instances. In order to do that you will have to add the following code in the settings.py file:
fleio edit settings.py
# instance traffic to display when collecting trafic data. Available options are 'public' and 'all'
INSTANCE_TRAFFIC_DISPLAY = 'public'
After editing settings.py file, press
Y when asked to restart Fleio.
