Logging HTTPS traffic

Hello,

I have a specific scenario in which I am trying to find out of a particular user visited a particular secure website on a particular day.
Is there a way to log HTTPS traffic via the firewalls built in monitoring? As far as I can see there is an HTTPS CA but no HTTPS traffic is showing up under Logging & Reporting > Web Security.

ASG V8 on 8.303

(I'm very new to this system)

Thanks
