springcloud-zinpin的安装与使用

springcloud-zipkin的安装与使用

1、什么是zipkin

　　一个分布式系统的调用跟踪监控系统，把每次微服务调用都埋上点，打印固定格式的日志，然后收集到zipkin中，然后zipkin做数据的统计与收集；

zipkin的收集有两种；

1、http收集

2、消息中间件收集

二、快速demo(以rabbitmq收集为例子)

项目工程步骤如下

创建springcloud的eureka，trace-1,trace-2,zipkin-server服务

1、springcloud的eureka

　　创建springboot工程　　

　　pom文件复制黏贴

application.properties文件如下：

spring.application.name=eureka-server
server.port=1001

eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

boot启动类加注解：

@EnableEurekaServer

2、创建trace-1、trace-2工程
pom文件

</project>

trace-1的配置文件

spring.application.name=trace-1
server.port=9101
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#eureka.client.serviceUrl.defaultZone=http://eureka.didispace.com/eureka/

spring.zipkin.enabled=true
spring.sleuth.sampler.percentage=1

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

trace-2的配置文件

spring.application.name=trace-2
server.port=9102
eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/
#eureka.client.serviceUrl.defaultZone=http://eureka.didispace.com/eureka/

spring.zipkin.enabled=true
spring.sleuth.sampler.percentage=1

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

trace-1启动类

@RestController
@EnableDiscoveryClient
@SpringBootApplication
public class Trace1Application {

    private final Logger logger = Logger.getLogger(getClass());

    @Bean
    @LoadBalanced
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @RequestMapping(value = "/trace-1", method = RequestMethod.GET)
    public String trace() {
        logger.info("===call trace-1===");
        return restTemplate().getForEntity("http://trace-2/trace-2", String.class).getBody();
    }
    public static void main(String[] args) {
        SpringApplication.run(Trace1Application.class, args);
    }

}

trace-2启动类

@RestController
@EnableDiscoveryClient
@SpringBootApplication
public class DemoApplication {
    private final Logger logger = LoggerFactory.getLogger(getClass());

    @RequestMapping(value = "/trace-2", method = RequestMethod.GET)
    public String trace(HttpServletRequest request) {
        logger.info("===<call trace-2, TraceId={}, SpanId={}>===",
                request.getHeader("X-B3-TraceId"), request.getHeader("X-B3-SpanId"));
        return "Trace";
    }
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

3、新建zipkin工程
pom文件

<?xml version="1.0" encoding="UTF-8"?>

        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>

            </plugin>
        </plugins>
    </build>

</project>

配置文件

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

spring.sleuth.enabled=false

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

启动类加上注解

@EnableZipkinStreamServer

二、四个工程一起启动

发起请求

localhost:9101/trace-1

浏览器进入localhost:9411

查看调用链
