How to properly clean logs in journald (systemd)

Question

Joomla

Faced with the fact that the logs /var/log/journal/began to occupy more than a gig.

$ journalctl --disk-usage 
Journals take up 1010.5M on disk.

But at the same time, it journalctldoes not contain any parameters and options that allow you to delete old entries: for example, those made before a certain date.
I rummaged through the config /etc/systemd/journald.conf- there is only about limiting the size of magazines.
I set the limit, but journalddid not cut the logs.
How to properly remove surplus?

Answer 1

To clear the logs according to the conditions: to a date or cut to such and such a size (in the number of records or in MB), you can use the built-in commands:

journalctl --vacuum-size=128M
journalctl --vacuum-time=1d

Answer 2

At the moment, I found only an offer on the net to stupidly delete the contents of the folder /var/log/journal/.
I did not delete everything, but only the files " *.journal~".
The folder is lighter by 600M. I don't see any bugs in my work.
But cleaning according to the conditions is of interest: to a date or cut to such and such a size (in the number of records or in MB).

Regular logrotate will not help?

Answer 5

$ pacman -Qi systemd
Название              : systemd
Версия                : 208-3
...
$ sudo systemctl start systemd-journal-flush

Description=Trigger Flushing of Journal to Persistent Storage
We check:
sudo journalctl --disk-usage

Answer 6

Why not just add log cleanup to crontab?
sudo crontab -e
there we add the desired schedule and insert the cleaning command. For example:
0 0 * * * journalctl --vacuum-time=1d
