侦探未将跟踪信息发送到Zipkin

问题描述

即使Zipkin运行正常，Sleuth也不会将跟踪信息发送到Zipkin.我正在使用Spring 1.5.8.RELEASE，Spring Cloud Dalston.SR4，并且在微服务中添加了以下依赖项:

Sleuth is not sending the trace information to Zipkin, even though Zipkin is running fine.I am using Spring 1.5.8.RELEASE, spring cloud Dalston.SR4 and I have added the below dependencies in my microservices:

<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>

我的日志总是错误的:[FOOMS，2e740f33c26e286d，2e740f33c26e286d，false]

My Logs are always coming false:[FOOMS,2e740f33c26e286d,2e740f33c26e286d,false]

我的Zipkin依赖项是:

My Zipkin dependencies are:

<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-server</artifactId>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-autoconfigure-ui</artifactId>
    <scope>runtime</scope>
</dependency>

为什么我在懒惰的陈述中变得虚假而不是真实?不过，会为所有调用正确生成traceId和SpanId.我的Zipkin在端口9411中运行

Why am I getting false instead of true in my slueth statements? The traceId and SpanId are properly generated for all the calls though. My Zipkin is running in port 9411

推荐答案

我发现我需要添加一个采样百分比.默认情况下，将发送零百分比的样本，这就是侦探没有向zipkin发送任何内容的原因.当我在属性文件中添加spring.sleuth.sampler.percentage=1.0时，它开始工作.

I found that I need to add a sampler percentage. By default zero percentage of the samples are sent and that is why the sleuth was not sending anything to zipkin. when I added spring.sleuth.sampler.percentage=1.0 in the properties files, it started working.
