On Linux you will find different solutions
for logging. Let's try to understand it all

2
00:00:11,329 --> 00:00:16,079
started with Syslog. Syslog is the legacy
service that takes care of logging, and it

3
00:00:16,079 --> 00:00:20,829
was implemented already in the old days
of Unix, so it has been around forever.

4
00:00:22,070 --> 00:00:25,230
Syslog on modern Linux
is implemented through R syslogd.

5
00:00:25,809 --> 00:00:30,524
We have seen a few alternatives as
well, but R syslogd is really the

6
00:00:30,524 --> 00:00:35,240
mature version, taking care of logging events
to files in the var log directory.

7
00:00:36,340 --> 00:00:42,939
And then came systemd, and systemd has taken care
of everything. So it also has its own logging service.

8
00:00:43,500 --> 00:00:47,585
The name is systemd Journald,
and on some distributions systemd

9
00:00:47,585 --> 00:00:51,670
Journald is the only logging
service that is still offered.

10
00:00:52,170 --> 00:00:57,590
But there's a couple of things you need to
know about that to find the appropriate log information.
