Introduction to Log Management with systemd
I’ve seen many Linux admins struggle with log management, especially when it comes to system services that are often overlooked. Systemd is a powerful system and service manager that provides a wide range of features, including process management, dependency handling, and log management. In this article, I’ll focus on using systemd to manage and rotate logs for system services.
Understanding systemd Logs
The real trick is to understand how systemd logs work. Systemd logs are stored in a binary format, which can be read using the journalctl command. This command provides a powerful way to filter, search, and manage system logs. By default, systemd stores logs in /var/log/journal, but this can be configured to use a different location. Don’t bother with trying to read the binary logs directly - just use journalctl.
