Log Files
Log files are text-based records generated by software applications, operating systems, or devices that document events, errors, and activities for debugging, monitoring, and auditing purposes. They provide a chronological history of system behavior, often including timestamps, severity levels, and contextual information to help developers and administrators understand what happened during execution.
Developers should learn to work with log files for troubleshooting issues, monitoring application performance, and ensuring system reliability in production environments. They are essential for debugging complex errors, analyzing user behavior, and maintaining compliance with security and operational standards in web servers, databases, and distributed systems.
