Introduction
Application Performance Monitoring (APM) tools help teams monitor, analyze, and optimize the performance of applications in real time. They provide deep visibility into application behavior by collecting and analyzing metrics such as response time, throughput, error rates, and transaction traces.
In modern environments powered by microservices, cloud-native architectures, APIs, and distributed systems, APM tools are essential. They enable teams to quickly detect bottlenecks, troubleshoot issues, and ensure a smooth user experience. With increasing system complexity, APM has evolved from basic monitoring to full-stack observability with AI-driven insights and automation.
