Monitoring and Logging
Monitoring and logging are essential practices in software development and operations for observing system behavior, performance, and health. Monitoring involves collecting and analyzing metrics in real-time to detect issues, while logging records detailed events and errors for debugging and auditing purposes. Together, they provide visibility into applications and infrastructure, enabling proactive management and troubleshooting.
Developers should learn monitoring and logging to ensure application reliability, performance optimization, and quick incident response, especially in production environments. Use cases include tracking user activity, identifying bottlenecks, detecting security breaches, and complying with regulatory requirements. These practices are critical for modern DevOps and cloud-native applications to maintain service-level agreements (SLAs) and improve user experience.
