Logs
Logs are chronological records of events, messages, or data generated by software applications, systems, or devices during their operation. They serve as a critical tool for monitoring, debugging, and auditing by capturing information such as errors, warnings, user actions, and system performance metrics. Logs are typically stored in files, databases, or centralized systems for analysis and troubleshooting.
Developers should learn and use logs to diagnose issues, track application behavior, and ensure system reliability, especially in production environments where real-time visibility is essential. Logs are crucial for debugging complex errors, monitoring performance bottlenecks, and meeting compliance requirements through audit trails, making them indispensable in DevOps, security, and operational contexts.
