Hi,
i had problems with several boot procedures on a SLES 12 SP4 host. So i wanted to have a look in the logs what happened.
But my journalctl just starts with a correct boot procedure which happened afterwards. Also using e.g. "--since yesterday" or "--since 2019-01-18" does not show previous information. There seems to be only one journal:
ha-idg-1:~ # ll /run/log/journal/
total 0
drwxr-s--- 2 root systemd-journal 60 Jan 21 12:52 444779a6db7e18b3bf8434ee5b7da073

Are there older logs, where can i find them ? Under /var/log/ i don't find anything appropriate.
How can i have a look further in the past ?

Thanks.

Bernd
