017 链路监控 SpringCloud Sleuth

一、引入依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>

日志级别debug模式

logging:
  level: debug

二、使用SpringCloud zipkin

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>

2.直接一个starter-zipkin 包含上面两个依赖

<!--  包含sleuth和zipkin-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>

3.配置zipkin Server

spring:
  zipkin:
    base-url: http://localhost:9411/ # 配置zipkin服务器地址
  sleuth:
    sampler:
      percentage: 1 # 设置发送百分比 1就是全发送

percentage springboot2.0可能不一样要查一下
