How to track the span through different dependencies with Sleuth?

Question

I'm learning how to track my distributed processes through all the microservices. I've been playing with Sleuth, Zipkin and different microservices, and it works fantastic! But when I try to do the same in a project interacting between the different dependencies I can not create the same behavior.

This image show how currently is working different microservices.

This is the diagram of microservices:

And this image show how works an application with dependencies.

This is the diagram of application with dependencies:

I wonder, is it possible to create the same behavior using dependencies as with microservices?

Yes, when you create a span you can set the service name. Just call newSpan.remoteServiceName(...)

I'm not using a custom span, only default values I mean I've set the property `spring.application.name` in each service to show their names... I will try to create a Span... – JUAN CALVOPINA M Sep 25 '18 at 15:54
I did not find a way to make it work with the `remoteServiceName` method, do you have an example? – JUAN CALVOPINA M Oct 06 '18 at 18:25

Taking the input of @MarcinGrzejszczak as reference, I resolved using a custom span:

Span remoteDependency = tracer.nextSpan()
                              .name("dependency_name") 
                              .start();

Where tracer is an autowired object from Trace:

@Autowired
private Tracer tracer;

Both classes are in brave package

import brave.Span;
import brave.Tracer;

Result:

If you want to take a look at the implementation in more detail, here is the sample: https://github.com/juanca87/sample-traceability-microservices
