RHEL Linux - Red Hat System Administration Practice Exam

What service is primarily responsible for managing system logs in Red Hat Linux?

1. rsyslog

2. systemd

3. logrotate

4. journalctl

The correct answer is: rsyslog

The primary service responsible for managing system logs in Red Hat Linux is rsyslog. Rsyslog is a rocket-fast system for log processing that provides a robust framework for logging, allowing administrators to efficiently manage, filter, and forward logs generated by various system services and applications. Rsyslog operates by gathering log messages from different sources, which can include the kernel, system services, and applications, and consolidating them. It provides various features like filtering, routing logs to different files, or even sending them to remote servers for centralized logging. This flexibility and capability make rsyslog the go-to tool for log management in many Linux systems, including Red Hat. Other options mentioned, such as systemd, relate to the overall initialization and management of system services rather than specifically handling logs. Logrotate is a tool used to manage the size of log files, rotating and compressing log files to prevent them from consuming too much disk space, but it does not manage logs in real-time like rsyslog. Journalctl is a command-line tool used to query and display logs from the journal managed by systemd, but it is not responsible for log management itself. It displays logs collected by the logging service, which in modern systems is typically journaled by
