Using Ntop to export/alert when new users join a Network

Hi all,

Just wondering if anyone is familar enough with ntop to help me out.

At the moment I have ntopng running on a Pi 3b+ thats connected via ethernet to my router and im using the web browser within the pi to access ntop (wish I could use my computer, but for some reason cannot).

Either way, does anyone know how to set up some form of alert so that when an individual joins/connects to the network, I am told (either through a log export ideally, or an email or other alert form) what the device name is, mac address, time since etc etc., essentially all the info that is located under the 'device' tab of ntop.

Thanks,
