将 OpenTelemetry 跟踪数据从 Spring 启动应用程序导入 Elastic APM - 视图缺少数据

Question

我有一个 Spring 启动应用程序，其中包含 Spring Cloud Sleuth、OpenTelemetry 工具和 OpenTelemetry 导出器 OTLP。

这是依赖的要点：

spring-cloud-starter-sleuth 没有 Brave，因为我们使用的是 OpenTelemetry 工具
spring-cloud-sleuth-otel-autoconfigure 引入了 OpenTelemetry 检测库并提供 Spring 自动配置

opentelemetry-exporter-otlp用于发送数据到apm服务器

   <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-sleuth</artifactId>
      <exclusions>
          <exclusion>
              <groupId>org.springframework.cloud</groupId>
              <artifactId>spring-cloud-sleuth-brave</artifactId>
          </exclusion>
      </exclusions>
  </dependency>

  <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-sleuth-otel-autoconfigure</artifactId>
  </dependency>

  <dependency>
      <groupId>io.opentelemetry</groupId>
      <artifactId>opentelemetry-exporter-otlp</artifactId>
  </dependency>
  <!-- https://mvnrepository.com/artifact/io.grpc/grpc-netty -->
  <dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-netty-shaded</artifactId>
      <version>1.43.0</version>
  </dependency>

我的 application.yml 中只有基本配置：

spring:
  sleuth:
    enabled: true
    otel:
      config:
        trace-id-ratio-based: 1.0
      exporter:
        otlp:
          endpoint: http://localhost:8200

通过此设置，我成功地在 APM 中看到了一些数据。示例屏幕：

但是，如果我查看 Elastic 文档，我会发现他们的屏幕显示了额外的数据：Traces。

对我来说，似乎缺少跨度和事务名称（我只看到 HTTP GET 而不是名称），至少它们存在于文档图像中。

有人知道为什么会发生这种情况以及如何解决这个问题吗？

这是 Elastic 中的示例跟踪文档：

Answer 1

To me, it looks like span and transaction names are missing (I only see HTTP GET instead of a name)

不，他们没有失踪。您看到 name 为 HTTP GET 的原因是由于偏好较少的基数名称和跟踪数据的语义约定。这里有关于 HTTP 跨度命名约定的详细解释 https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/semantic_conventions/http.md#name。 auto-instrumentation 库生成的任何数据都将遵守语义约定规范。我猜来自链接供应商的可视化来自手动检测，您作为最终用户可以在其中给出任何名称（尽管建议每个人都使用较少的基数，但那里没有强制执行）。我不认为这里有什么可以“修复”的。
