I guess this will be logging that type of data, so another data logger.
Little Snitch is not a data logger. It's a real time connection monitor.
Let's say you're using an app, and it decides to make a random connection to some server. Little Snitch will immediately pop up a dialog asking what you want it to do - let the connection through, block the connection, and if you want to allow it always, block it always, etc.
The fact it's immediate generally is for tracking purposes - the event happened because you clicked a button or started an app. A logger just makes an entry in the log, and it's really hard to correlate that log with user activity. Maybe you were running Audacity, and when you start it up, it makes a connection to the owner's server completely out of the blue. Maybe it's checking for an update. Maybe it's trying to upload your data to its servers. What you learn is that it happened when it was launching. With a data logger, you just get notified of it but have no way to figure out what you were doing at the time of the log entry.
In this day and age of telemetry and such, having it show up immediately when an app tries to make the connection is far more useful than having to do rules of allow and deny lists and having no clue what's causing it. Knowing it was a specific app uploading all your personal information means you can choose to switch to something better, block the upload so you can continue to use the app, or some other thing.
