FastAPI with Observability
A FastAPI observability demo implementing traces (Tempo), metrics (Prometheus), and logs (Loki) with OpenTelemetry and Grafana.
What is FastAPI with Observability?
FastAPI Observability is a demonstration project that shows how to implement comprehensive observability for FastAPI applications using the Grafana stack (Prometheus, Tempo, Loki) and OpenTelemetry. It provides a working example of instrumenting FastAPI to collect traces, metrics with exemplars, and correlated logs, then visualizing them in Grafana with seamless navigation between telemetry data.
Backend developers and DevOps engineers building or monitoring FastAPI services who want to implement production-grade observability with open-source tools.
It offers a complete, ready-to-run reference implementation that saves time compared to piecing together observability components manually, and demonstrates best practices like trace-to-log correlation and metrics exemplars that are often poorly documented.
Overview
Observe FastAPI app with three pillars of observability: Traces (Tempo), Metrics (Prometheus), Logs (Loki) on Grafana through OpenTelemetry.
