Where are Journald logs stored?
The logs are still kept in a text file under /var/log unless you have activated the use of persistent journald log by creating /var/log/journal directory.
How do I clear var log journal?
Yes you can delete everything inside of /var/log/journal/* but do not delete the directory itself. You can also query journalctl to find out how much disk space it’s consuming: $ journalctl –disk-usage Journals take up 3.8G on disk.
Is Journald part of systemd?
The journal is controlled by the systemd-journald daemon. It collects information from different sources and loads the messages into the journal.
What is a VAR log?
The main log file a) /var/log/messages – Contains global system messages, including the messages that are logged during system startup. There are several things that are logged in /var/log/messages including mail, cron, daemon, kern, auth, etc.

conf files located in /etc/systemd. Unit files are stored in the /usr/lib/systemd directory and its subdirectories, while the /etc/systemd/ directory and its subdirectories contain symbolic links to the unit files necessary to the local configuration of this host.
Why is the / var / log / journal folder so big?
I don’t understand why the /var/log/journal/ folder is so big. For example, by executing the command systemctl -f, i see the fill. If I click on an email on Thunderbird, it generates dozens of lines that I consider useless. Currently, I have more than 1.5GB ( du -h /var/log/journal/) generated in 1 day!
How does the rotation effect the journal file?
The rotation has the effect that all currently active files are archived (and potentially new, empty journal files opened as replacement), and hence the vacuuming operation has the greatest effect as it can take all log data written so far into account.
Can a vacuum file reduce the number of journal files?
Similarly, –vacuum-files= might not actually reduce the number of journal files to below the specified number, as it will not remove active journal files.
