Logging Wifi Usage

[ammonsc]

I use the following script originally created by @delbrown here: Manage WiFi on macOS

I modified it to warn the users using JAMFHelper and allow them to stay connected.

I would like to add some logging to it so I can see how many times a user connects to a non-work network and how often they stay connected or disconnect.

Any help is much appreciated.
