Check to see who has been log-in to your Laravel App

I have about 5000 users registered in my site. I should have implement the log-in count, and keep incrementing it right after the user logged-in, but I didn't know about that until now. :(

Is there still a way of to see or know who have been loggin in ?

Is there any logs in the linux that I can make a useful of ?

I just want to know which emailed has been use to logged in.

Any hints / suggestions on that will be much appreciated !
