Application Monitoring
Application monitoring is the practice of tracking and analyzing the performance, availability, and health of software applications in real-time or near-real-time. It involves collecting metrics, logs, and traces to detect issues, optimize performance, and ensure reliability. This helps teams proactively identify problems like slow response times, errors, or resource bottlenecks before they impact users.
Developers should learn application monitoring to build more reliable and performant software, especially in production environments. It is crucial for modern distributed systems, microservices architectures, and cloud-native applications where issues can be complex and hard to debug. Use cases include setting up alerts for downtime, analyzing user experience, and optimizing resource usage to reduce costs and improve scalability.
