Automatic Microservices Observability with Open-Source Progr
summary
Ballerina automatically instruments network operations and emits metrics and traces after flipping a config flag; it exposes a Prometheus endpoint and publishes traces to Jaeger, visualized in Grafana, all run via Docker. Demo builds a geolocation service that calls external APIs, adds an in-memory cache and a MySQL-backed cache, and shows propagated spans across services plus SQL metrics—everything works live and requires no manual tracing code beyond optional span annotations.
