ZipkinSpanReporter 无法正常工作

Question

我正在尝试评估 zipkin 以便为我们所有的微服务启用分布式跟踪功能。以下是我设置中的版本。

Spring-引导版本：1.5.7.RELEASE
spring-云版： 卡姆登.SR6
zipkin 版本：2.2.1

application.properties
中的 seluth 配置

spring.sleuth.sampler.percentage=1.0

spring.sleuth.web.skipPattern=(^cleanup.|.+favicon.)

然后我创建了 ZipkinSpanReporter bean，如下所示。请注意，我已将 Eureka 服务器设置为所有微服务，甚至是向 Eureka 服务器注册的 zipkin 服务器，以便 Zipkin 客户端可以通过 eureka

解析 zipkin 服务器

 @Bean
    public ZipkinSpanReporter makeZipkinSpanReporter() {
        return new ZipkinSpanReporter() {
            private HttpZipkinSpanReporter delegate;
            private String baseUrl;

            @Override
            public void report(Span span) {

                InstanceInfo instance = eurekaClient
                        .getNextServerFromEureka("zipkin", false);
                if (!(baseUrl != null &&
                        instance.getHomePageUrl().equals(baseUrl))) {
                    baseUrl = instance.getHomePageUrl();
                    delegate = new HttpZipkinSpanReporter(baseUrl,
                            zipkinProperties.getFlushInterval(),
                            zipkinProperties.getCompression().isEnabled(),
                            spanMetricReporter);

                    if (!span.name.matches(skipPattern)) delegate.report(span);
                }
            }
        };
    }

我观察到的是，当我检查 zipkin 时，zipkin 客户端（书籍）没有将所有跨度报告回 zipkin 服务器。报告了一些，几乎所有跨度都被删除了

我已经为

启用了日志记录

logging.level.org.springframework.cloud.sleuth.instrument.web=DEBUG
logging.file=book.log

以下是日志信息：

但是我无法从 zipkin 控制台

中找到记录在 book.log 文件中的 traceId

你能解释一下为什么很多 span 没有报告给 zipkin 服务器吗？

提前致谢。

Answer 1

您的代码很可能已损坏。您可以查看 https://github.com/spring-cloud/spring-cloud-sleuth/blob/master/spring-cloud-sleuth-zipkin/src/main/java/org/springframework/cloud/sleuth/zipkin/ZipkinAutoConfiguration.java class 我们为 Edgware 添加了负载平衡 zipkin 服务器解析的位置。

Answer 2

您使用的是 baeldung 教程中的代码示例是否正确？ (http://www.baeldung.com/tracing-services-with-zipkin - 3.2.Spring 配置)

我认为第 34 行和第 35 行（右大括号）有错误。

我已经通过修改方法解决了这个问题：

@Bean
public ZipkinSpanReporter makeZipkinSpanReporter() {
    return new ZipkinSpanReporter() {
        private HttpZipkinSpanReporter delegate;
        private String baseUrl;

        @Override
        public void report(Span span) {

            InstanceInfo instance = eurekaClient
                    .getNextServerFromEureka("zipkin", false);
            if (!(baseUrl != null &&
                    instance.getHomePageUrl().equals(baseUrl))) {
                baseUrl = instance.getHomePageUrl();
                RestTemplate restTemplate = new RestTemplate();
                zipkinRestTemplateCustomizer.customize(restTemplate);
                delegate = new HttpZipkinSpanReporter(
                        restTemplate,
                        baseUrl,
                        zipkinProperties.getFlushInterval(),
                        spanMetricReporter);
            }

            if (!span.name.matches(skipPattern)) {
                delegate.report(span);
            }
        }
    };
}

也许这可以帮助某人或来自 baeldung 的人阅读本文并验证和更正代码示例。 ;)
