Notes journalctl service triage

journalctl service triage

Fast systemd log checks for a failed Linux service.

Commands

systemctl status example.service
journalctl -u example.service --since "30 minutes ago" --no-pager
journalctl -p warning..alert --since today --no-pager

Reminder

Check the unit name, recent config changes, and whether the failure is repeatable before editing the service file.
