How do I configure systemd journalctl for better logging?
You can configure systemd journalctl by editing the configuration file located at /etc/systemd/journald.conf. What specific logging improvements are you looking for?
I want to limit the size of the logs and set a retention policy.
To limit the size of the logs, you can set the 'SystemMaxUse' and 'SystemKeepFree' options in the journald.conf file. For retention, use 'SystemMaxFileSize' and 'SystemMaxFiles'.
Can you give me an example of how to set these options?
Sure! You can add the following lines to your journald.conf:
[Journal]
SystemMaxUse=100M
SystemKeepFree=50M
SystemMaxFileSize=20M
SystemMaxFiles=5
This will limit the total log size to 100MB and keep at least 50MB free.
Thanks! How do I apply the changes?
After editing the configuration file, run sudo systemctl restart systemd-journald
to apply the changes.
