FastAPI Observability

Structured logging in FastAPI captures logs as JSON with request context, enabling consistent parsing and filtering across your application. This Skill provides middleware and configuration patterns to bind request metadata to logs automatically, making it easier to trace issues in production.

Yes. This Skill covers adding Prometheus counters and histograms to FastAPI endpoints and exposing them at /metrics. Custom decorators and middleware instrument request latency and throughput for integration with Grafana dashboards.

OpenTelemetry integration provides distributed tracing across FastAPI services. This Skill configures tracing middleware and telemetry exporters to correlate requests end-to-end, enabling you to debug latency and failures across microservices.

While each serves a distinct purpose, this Skill bundles production-ready patterns for all three: structured logging middleware, Prometheus metrics decorators, and OpenTelemetry tracing configuration. You can deploy them together or independently.

Health checks and monitoring endpoints expose application state to orchestrators and monitoring systems. This Skill includes ready-to-deploy patterns for health check endpoints and configurations compatible with Grafana and observability platforms.

Yes. This Skill provides configurable logging formats supporting both human-readable and JSON output, allowing you to adapt log structure for development, staging, and production without code changes.
