#Systemd - How to read live-tail logs of multiple services with journalctl

sudo journalctl --follow _SYSTEMD_UNIT=docker.service + _SYSTEMD_UNIT=apache2.service

Hint:
https://serverfault.com/questions/805775/journalctl-how-to-display-colors-in-its-output/893763#893763

If the original daemon output is already colorized, but the colors are being lost when using journalctl, the `--output cat` option will restore them.
