I have some clients (at least one) that is using a massive amount of data. Some devices such as IoT devices are connected all the time. Other clients such phones and laptops are connected on and off.
I can easily set fixed IP addresses on all devices so I can see which client (IP) is using most data. But what is the best way to start logging data usage per client to find which client is utilizing most data on a 30 day period?
