Runtime Monitoring
Runtime monitoring is a software engineering practice that involves observing and analyzing the behavior of a system while it is executing, typically in production environments. It collects metrics, logs, and traces to detect performance issues, errors, and security threats in real-time. This enables proactive maintenance, debugging, and optimization of applications.
Developers should learn runtime monitoring to ensure application reliability, performance, and security in live deployments, as it helps identify bottlenecks, failures, and anomalies that are hard to replicate in testing. It is essential for modern DevOps and cloud-native applications, where continuous monitoring supports incident response, capacity planning, and user experience improvements.
