Users login log and activities

Can I see when a user login to the PBX server and what activities he’s doing? For example the user access CDR report, monitoring call, etc?

I dont see anything like that in /var/log/asterisk/full

I can see who is online from the console using command “who” but how to know their activities? Where is the log file?

FYI, I’m login with root account.

Thanks
