Centralized Logging and Rotation with journald and logrotate
Keep automated systems healthy by reading systemd logs with journalctl and preventing log files from filling disks using logrotate.
Automation Needs Logs
Cron jobs, systemd services, and shell functions all produce output. To run unattended systems you must capture, search, and rotate that output. Enter journalctl and logrotate.
What Is journald?
systemd-journald collects logs from services you manage with systemctl into a structured binary journal you query with journalctl.
