On Linux you will find different solutions for logging. Let's try to understand it all
started with Syslog. Syslog is the legacy service that takes care of logging, and it
was implemented already in the old days of Unix, so it has been around forever.
Syslog on modern Linux is implemented through R syslogd.
We have seen a few alternatives as well, but R syslogd is really the
mature version, taking care of logging events to files in the var log directory.
And then came systemd, and systemd has taken care of everything. So it also has its own logging service.
The name is systemd Journald, and on some distributions systemd
Journald is the only logging service that is still offered.
But there's a couple of things you need to know about that to find the appropriate log information.
