I am using journalctl for logging, it appears to be only keeping logs for 1 hour, how can I force it to keep 30 days of logs?

Reset to default

Double check your journald.conf file. Probably you are not using defaults values for SystemMaxUse or MaxFileSec. If you want 30 days of logs, use MaxFileSec=30day. Then restart the journal with systemctl restart systemd-journald

Also check how much space you are using for logs at the moment with journalctl --disk-usage and how much free space you have in your disk df -lh. Perhaps if you have little free space, that is triggering a vacuuming operation.
