Vert.x Opentracing example

Here you will find examples demonstrating Vert.x Opentracing in action.

Please consult the Vert.x Opentracing for the detailed documentation.

Microservices

This example shows a couple of simple microservices monitored with Vert.x Opentracing

The Joke service provides an HTTP microservice for jokes stored in a PostgreSQL.

The HTTP server and the database client contribute traces.

You can query this service with curl:

> curl http://localhost:8082

The Hello service provides an HTTP microservice for saying hello. This service uses the Joke service to tell the user a joke.

The HTTP server and the HTTP client contribute traces.

You can query this service with curl:

> curl http://localhost:8081

The Gateway is a simple HTTP gateway that exposes both Joke and Hello services.

The HTTP server and the HTTP client contribute traces.

You can query this service with curl:

> curl http://localhost:8080/hello
> curl http://localhost:8080/joke

You need to start an Opentracing server, such as Jaeger

> docker run -d -p5775:5775/udp -p6831:6831/udp -p6832:6832/udp -p5778:5778 -p16686:16686 -p14268:14268 -p9411:9411 jaegertracing/all-in-one:0.8.0

Jaeger provides a visual console

You can run the Hello, Joke and Gateway services in your IDE with Opentracing Example

Or you can start them separately:
