APM
Software tooling that measures and tracks application performance in real time.
Definition
APM, or Application Performance Monitoring, is a category of software tooling that measures, tracks, and manages the performance and availability of applications. It helps engineering teams understand how an application is behaving in production and diagnose bottlenecks before they affect users.
In depth
Traditional APM focuses on response times, error rates, and throughput for web applications and services. Modern APM has evolved into full-stack observability, incorporating distributed traces, infrastructure metrics, and real user monitoring (RUM) in a single platform. APM tools typically instrument application code via agents or SDKs and visualise the resulting telemetry in dashboards, flamegraphs, and service maps. obseria.io provides OpenTelemetry-native APM with automatic instrumentation for Node.js, Python, Java, Go, and .NET.
