第七次课：Micrometer Tracing服务跟踪

前言

• 跨微服务的API调用发生异常,要求快速定位(比如5分钟以内)出问题出在哪里,

该怎么办?

• 跨微服务的API调用发生性能瓶颈,要求迅速定位(比如5分钟以内)出系统瓶颈,

该怎么办?

简单使用Micrometer Tracing

加依赖

在父级pom.xml中加依赖

<properties>
    <micrometer-tracing.version>1.2.0</micrometer-tracing.version>
    <micrometer-observation.version>1.12.0</micrometer-observation.version>
    <feign-micrometer.version>12.5</feign-micrometer.version>
    <zipkin-reporter-brave.version>2.17.0</zipkin-reporter-brave.version>
  </properties>

配置

# ========================zipkin===================
management:
  zipkin:
    tracing:
      endpoint: http://localhost:9411/api/v2/spans
  tracing:
    sampling:
      probability: 1.0 #采样率默认0.1(10次只能有一次被记录)，值越大越及时

访问zipkin
