By default systemd-journald logs all events that are happening in the system into a single centralized database in /run/log.

You can filter out the log entries made by the user by using "_UID" field.

ex: journalctl _UID=1000 _COMM=su This will show all the logs associated with the user id 1000.

The journals in the /run/log are non-persistent(cleared off at reboot). For persistence you need to modify the journald.conf file.

Go to /etc/systemd/journald.conf and uncomment the following line.

Storage=auto.

Then create a "journal" dir in /var/log and reload systemd-journald. sudo killall -USR1 systemd-journald.
