quarkus-observability-demo

This is a collection of small project demonstrating Observability features on quarkus.

The projects based on the quarkus-quickstarts with a set of REST endpoints, using hibernate, panache and a Postgres database. All use OpenTelemetry for tracing and Micrometer for metrics.

The reference project is quarkus-observability-demo-resteasy. All others have small variations.

Each project has a specific readme with instructions. Infraestructure required by the projects is deployed with Docker Compose and for the quarkus-observability-demo-full project, with Openshift.
