Application Performance Monitoring
Application Performance Monitoring (APM) is a set of tools and practices used to track and analyze the performance, availability, and user experience of software applications in real-time. It involves collecting metrics like response times, error rates, and resource utilization to identify bottlenecks and optimize application behavior. APM helps ensure applications meet performance standards and provides insights for debugging and scaling.
Developers should use APM when building or maintaining production applications to proactively detect performance issues, reduce downtime, and improve user satisfaction. It is essential for web applications, microservices architectures, and cloud-based systems where monitoring latency, throughput, and errors is critical for maintaining service-level agreements (SLAs) and optimizing resource usage.
