Access log B&B and hotel Wi-Fi

[fox983]

Hi all :),
I'd like to know if is it possible to schedule sending a mail with an Insight report every day (like "Export" function in web page), or if I must use ntop for this...
Or in any case what is the best practice for traffic log, offering Wi-Fi access in B&B with 1 or 2 access point, to give all possible informations in case of request from the authorities (IP, MAC address, history of connection)?
Thank you all!
