So that is my question. I googled it but nothing came. I see that the logs I have only covers 24 hours (if the time is not wrong, because it resets on every boot)

  • In Ubuntu it's usually 30 days, not sure about "Linux systems" in general. Other distros may have different preferences. – mikewhatever Apr 30 '17 at 18:45

Logs are controlled by logrotate. It keeps a configurable number of *.log.1, *.log.2.gz, ... files (compressing old ones).

See man logrotate, /etc/cron.daily/logrotate and /etc/logrotate.conf.

Reading logs can most easily be done with journalctl - see man journalctl, and this article
