Zipkin未显示跟踪日志
[英]Zipkin not showing trace logs
问题描述
Hi Hoping somebody can help am trying to get a very basic implementation of zipkin working to get to grips with distributed tracing. 
您好，希望有人能帮助您获得zipkin的一个非常基本的实现，以帮助您掌握分布式跟踪。 I am using the spring boot to do this but cannot seem to get it to work. 我正在使用弹簧靴来执行此操作，但似乎无法使其正常工作。 Nothing appears in the zipkin UI when I try to find traces for a my service. 当我尝试查找服务跟踪时，zipkin UI中什么也没有出现。
I have got 2 deployments as follows: 我有2个部署，如下所示：
My spring boot app which I am wanting to log: 我想登录的我的spring boot应用程序：

With these dependencies I do get a connect error because of the rabbit mq dependency. 有了这些依赖关系，由于Rabbit mq依赖关系，我确实出现了连接错误。 I had to include this becuase I got a META-INF/spring binders error. 因为我遇到了META-INF / spring活页夹错误，所以我不得不将其包括在内。 Wasnt really sure how to get around this other than putting the dependency in. 除了确定依赖关系之外，是否真的确定如何解决这个问题。
My application.class 我的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. 当我运行此应用程序并调用端点时，通过日志可以看到它应该将其发送到zipkin。

This are my full logs. 这是我的完整日志。 Again I get the rabbitmq exception but not sure why i actually need this. 再次，我得到了rabbitmq异常，但不确定为什么我实际上需要这个。 Can zipkin not work without it 没有它，zipkin不能工作吗

Here you have a very basic example of Sleuth & HTTP communication. 在这里，您有一个Sleuth和HTTP通信的非常基本的示例。 https://github.com/openzipkin/sleuth-webmvc-example You can set your dependencies in a similar manner and everything should work fine. https://github.com/openzipkin/sleuth-webmvc-example您可以以类似的方式设置依赖项，并且一切正常。 In your example you've got Stream but I don't think you're using it so it's better to remove it. 在您的示例中，您拥有Stream，但我不认为您正在使用它，因此最好将其删除。

As M.Deinum said remove stream and stream-rabbit dependencies what if you do not need some AMQP server to store the trace message. 正如M.Deinum所说，删除stream和stream-rabbit依赖关系，如果不需要某些AMQP服务器来存储跟踪消息该怎么办。
or 要么
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: 从应用程序配置（两者）配置AMQP（代码中的rabbitMQ）并在zipkin-server端添加zipkin-stream和stream-rabbit ，因此这一次您的应用程序（ zipkin-client ）将不直接与zipkin-server和这将是：
zipkin-client <==> AMQP(rabbitMQ) <==> zipkin-server

You will need rabbitMQ(or any JMS server) to send the logs to zipkin. 您将需要RabbitMQ（或任何JMS服务器）将日志发送到zipkin。
You can refer to below tutorial to get more idea about it. 您可以参考下面的教程以了解更多信息。

On high level you can follow below steps 在较高级别，您可以按照以下步骤操作
Download the zipkin server
下载zipkin服务器 After downloading the jar file fire below command to start the zipkin server
下载完jar文件后，执行以下命令启动zipkin服务器 java -jar zipkin.jar
java -jar zipkin.jar
This will start the zipkin server on http://localhost:9411 3. Add below entry in your pom file 这将在http：// localhost：9411上启动zipkin服务器。3.在pom文件中添加以下条目
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
Add below entry in application.properties file to specify the zipkin server
在application.properties文件中添加以下条目以指定zipkin服务器 spring.zipkin.base-url= http://localhost:9411/
spring.zipkin.base-url = http：// localhost：9411 / spring.sleuth.sampler.probability=1
spring.sleuth.sampler.probability = 1
