Demo for gRPC instrumentation with sleuth

This projects has two modules, grpc-client and grpc-server

For bothb of them, to see traces on zipkin you should start a zipkin server on port 9411

For example with docker:

docker run -d -p 9411:9411 openzipkin/zipkin

Modules

grpc-client

A webflux application that publish a reactive endpoint an call grp-server using a reactive grpc client stub

You can run it with:

mvn spring-boot:run

grpc-server

You can run it with:

mvn spring-boot:run

Testing application

http://localhost:8080/hello/<yourName>;. Then search traces at http://localhost:9411/zipkin/

You can change spring-cloud-dependencies version setting property spring-cloud-dependencies.version at root project pom.xml.Trace is good for Hoxton.SR2, but not foe next versions. The difference only occurs if we have a subscribeOn on MyController#hello
