Basic Logging
Basic logging is a fundamental software development practice that involves recording events, messages, and data during program execution to aid in debugging, monitoring, and auditing. It typically includes writing log entries to files, consoles, or other outputs with timestamps and severity levels (e.g., INFO, ERROR, DEBUG). This provides a chronological trail of application behavior for troubleshooting and analysis.
Developers should learn and use basic logging to diagnose issues in production environments where debugging tools are unavailable, track application flow for performance optimization, and maintain audit trails for security and compliance. It is essential for any non-trivial application, especially in distributed systems, web services, and long-running processes where real-time monitoring is critical.
