Logging
Logging is a software development practice that involves recording events, messages, and data during the execution of an application to monitor its behavior, diagnose issues, and analyze performance. It provides a chronological record of activities, errors, and state changes, which is essential for debugging, auditing, and operational insights. Logs are typically stored in files, databases, or centralized systems for later review and analysis.
Developers should implement logging to enable effective debugging and troubleshooting, especially in production environments where direct access to the application is limited. It is crucial for monitoring application health, detecting anomalies, and ensuring compliance with regulatory requirements through audit trails. Logging is widely used in distributed systems, web applications, and microservices to trace requests, identify bottlenecks, and improve reliability.
