Where is the SSH log path?

Hello, for security checks reasons im looking for the log of the SSH login attemps on my OSMC running on a Raspberry 3.
I saw in forums around internet that the path in debian is /var/log/auth.log but i dont see that file in my system.
Where i can find the log of the ssh login attemps in my raspberry’s OSMC?
Thanks
Regards

journalctl

sudo journalctl _COMM=sshd

That’s a new one for me! It doesn’t appear in the jessie man page but is there in the stretch man page. But it works on jessie, as well. Also it’s not in the Ubuntu 16.04 man page but again works!

There’s also sudo journalctl -t sshd on stretch (and Ubuntu 16.04) but doesn’t work on jessie.

Thanks to all!
