System Logs

Linux maintains logs documenting system activities, errors, and kernel messages. Boot logs record all operations during system startup for troubleshooting. Use dmesg to view kernel ring buffer messages in real-time, or access logs in /var/log. Systemd uses journalctl for logging. Log levels range from emergency (system unusable) to debug messages.
