Spring Boot Sleuth and ZipKin

This post is my implementation of the post here: https://reflectoring.io/tracing-with-spring-cloud-sleuth/

Although the post already included the source code, but it is still pretty hard for me to start

So I created this post to help me to remember how to make Slueth and Zipkin work.

Spring Cloud Sleuth

will add traceId and spanId to logger

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-sleuth</artifactId>
  <version>${spring-cloud.version}</version>
</dependency>

Analyze Traces with ZipKin

Logger collector and analytics

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-zipkin</artifactId>
  <version>${spring-cloud.version}</version>
</dependency>

spring.sleuth.sampler.percentage=1.0

Is percentage of sampler, the default value is 0.1 ( 10%) that means you only take 10% of request to sampler

Change to 1.0 ( 100% ) to sample all of request.
