Log Management Development Tutorials, Guides & Insights

Log management is a critical aspect of system administration in Linux. Logs provide invaluable information for troubleshooting, security audits, and system performance monitoring. Two powerful tools commonly used for log management in Linux are journalctl and rsyslog. This tutorial will guide you through managing Linux logs using these tools, covering everything from basic log viewing to advanced log configuration and filtering.

Before diving into journalctl and rsyslog, it's important to understand how logging works in Linux:

MySQL generates various log files, each serving a specific purpose:

• Error Log: Records problems encountered during server operations.
• General Query Log: Logs all queries sent to the server.
• Slow Query Log: Captures queries that take longer than a specified duration to execute.
• Binary Log: Used for replication and data recovery.
