Zipkin not showing trace logs

Hi Hoping somebody can help am trying to get a very basic implementation of zipkin working to get to grips with distributed tracing. I am using the spring boot to do this but cannot seem to get it to work. Nothing appears in the zipkin UI when I try to find traces for a my service.

I have got 2 deployments as follows:

My spring boot app which I am wanting to log:

</project>

With these dependencies I do get a connect error because of the rabbit mq dependency. I had to include this becuase I got a META-INF/spring binders error. Wasnt really sure how to get around this other than putting the dependency in.

My application.class

package com.example.demo;

import java.util.logging.Level;
import java.util.logging.Logger;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.sleuth.sampler.AlwaysSampler;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
@RestController
public class ZipkinApplication {

    private static final Logger LOG = Logger.getLogger(ZipkinApplication.class.getName());

    @Autowired
    private RestTemplate restTemplate;

    public static void main(String[] args) {
        SpringApplication.run(ZipkinApplication.class, args);
    }

    @Bean
    public RestTemplate getRestTemplate() {
        return new RestTemplate();
    }

    @Bean
    public AlwaysSampler defaultSampler() {
      return new AlwaysSampler();
    }

    @RequestMapping("/zipkin")
    public String home() {
        LOG.log(Level.INFO, "you called home");
        return "Hello World";
    }

    @RequestMapping("/callhome")
    public String callHome() {
        LOG.log(Level.INFO, "calling home");
        return restTemplate.getForObject("http://localhost:8080/zipkin", String.class);
    }
}

When I run this aplication and call my endpoint I can see through the logging that it should be sending it to zipkin.

2017-05-17 15:20:09.425  INFO [zipkin demo,13ad9334863d28cf,13ad9334863d28cf,true] 23980 --- [nio-8080-exec-1] com.example.demo.ZipkinApplication       : calling home

This are my full logs. Again I get the rabbitmq exception but not sure why i actually need this. Can zipkin not work without it

My application.class

package com.example.zipkinClient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ZipkinClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinClientApplication.class, args);
    }
}

application.properties

spring.application.name=zipkin server
server.port=9411

Running the zipkin server it starts up ok but nothing is shown in the trace logs excpet for an error

When I go to the client I do get this error though

As M.Deinum said remove stream and stream-rabbit dependencies what if you do not need some AMQP server to store the trace message.

config the AMQP(rabbitMQ in your code) from application-configuration(both) and add zipkin-stream & stream-rabbit in zipkin-server side, so this time your app(zipkin-client) will not direct connect with zipkin-server and it will be:

zipkin-client <==> AMQP(rabbitMQ) <==> zipkin-server

Here you have a very basic example of Sleuth & HTTP communication. https://github.com/openzipkin/sleuth-webmvc-example You can set your dependencies in a similar manner and everything should work fine. In your example you've got Stream but I don't think you're using it so it's better to remove it.
