Episode 39 — Linux Logging: Syslog, Journald, and Log Rotation

Visibility defines resilience, and this episode explains how Linux records the events that matter. You’ll learn the roles of Syslog and Journald, how they differ, and how both feed centralized logging pipelines. We break down message priorities, facilities, and formats to help you interpret logs efficiently and distinguish noise from actionable data. You’ll also hear how to configure log destinations—whether local files, remote collectors, or SIEMs—and why timestamp integrity and retention policies are crucial for audits and incident response.Listeners will then explore log rotation as a preventive control against both storage exhaustion and data loss. The episode covers configuration best practices, such as compression, archival, and permission settings, ensuring logs remain tamper-evident and recoverable. You’ll come away with a clear mental model for how Linux logging connects operational awareness to compliance evidence. In both the exam and real-world analysis, understanding where messages originate and how they propagate transforms chaos into clarity.
