Metrics And Monitoring
Metrics and monitoring is a software engineering practice focused on collecting, analyzing, and visualizing quantitative data about system performance, health, and behavior. It involves tracking key indicators like response times, error rates, resource utilization, and business metrics to ensure reliability and optimize operations. This enables teams to detect issues, understand trends, and make data-driven decisions for maintaining and improving systems.
Developers should learn and implement metrics and monitoring to ensure system reliability, performance optimization, and proactive issue detection in production environments. It is essential for modern distributed systems, microservices architectures, and cloud-native applications where visibility into complex interactions is critical. Use cases include setting up alerts for anomalies, capacity planning, debugging performance bottlenecks, and meeting service-level objectives (SLOs).
