Posted 2021-03-24

1.【微服务】依赖:

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

2.每个【微服务】加配置

spring:
        zipkin:
                base-url: http://tsca.cc:6500
                # 不把该地址当做【微服务】
                discoveryClientEnabled: false
     sleuth:
                sampler:
                        # 抽样率: 1.0=>100%  默认: 0.1=>10%
                        probability: 1.0

3.搭建 【zipkin】 面板
