前言

Distributed tracing for spring cloud（Github）

spring-cloud/spring-cloud-sleuth为链路跟踪工具，可以在日志中生成链路跟踪记录

Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data.（Github）

openzipkin/zipkin为图表生成工具，可以搭配Sleuth将链路信息生成图表展示

rabbitmq/rabbitmq-server配合spring-cloud/spring-cloud-sleuth和openzipkin/zipkin实现解耦和流量削峰

Sleuth

添加依赖

  • Sleuth只需要添加依赖即可完成配置，无需额外配置
pom.xml

    username: admin
    password: admin
  zipkin:
    sender:
      type: RABBIT

配置链路抽样比例（可选）

spring:
  sleuth:
    sampler:
      probability: 0.1

启动Zipkin

  • 启动Zipkin时，要连接RabbitMQ

下载Jar包

运行Jar包

1
java -jar zipkin-server-2.12.9-exec.jar --zipkin.collector.rabbitmq.uri=amqp://admin:admin@192.168.64.140:5672

完成
