Observable Elixir
summary
A demo Elixir microservice and Docker Compose stack ships working observability: instrumented with :telemetry events, structured logs in logfmt sent to Grafana Loki, Prometheus-style metrics exposed by PromEx on a /metrics endpoint, and OpenTelemetry traces exported (W3C Trace Context propagation) to Tempo. Generators add a PromEx config and plugins, five libraries wire Phoenix/Tesla/Ecto, trace IDs appear in logs, and Grafana dashboards and alerts are pre-built and verified.
