Internet Traffic Reporting Device

[Dynamite-M2]

I'm looking for a device I can insert between my home modem and router that will log internet traffic and email a daily report. My concern is that it might slow down the network or cause interference. But surely there is something out there. If you have a suggestion please share? Thanks!

Managed switch setup to SPAN your interface to the ISP or your router. Set a SPAN member interface on that switch to connect to a machine running Security Onion.

What does "log internet traffic" mean to you?
What addresses are accessed?
How much traffic comes in/goes out? And Where it goes?
Wireshark style "logging"? (AVM fritzbox devices can do that)
