How to clear systemd journal logs by time
How to clear systemd journal logs by time?
Run the journalctl command and define a vacuum time to clear out the journal logs.
journalctl --vacuum-time=TIMEThe journalctl command can be used to remove older journal logs by using the --vacuum-time option, followed by a time. This time defines the maximum age of entries and items that are too old will be purged from the logs. This is a useful option to regain disk space when the logs are using too much of it.
Usage
Before clearing out any journal logs, it may be useful to see the current disk usage first. Use the --disk-usage option to show
# journalctl --disk-usage
Archived and active journals take up 256.0M in the file system.
To remove all journal logs older than 30 days, define ‘30d’ as its period.
# journalctl --vacuum-time=30d
