我有一个带有Spring Cloud Sleuth、OpenTelemetry instrumentation和OpenTelemetry exporter OTLP的Spring Boot应用程序。

以下是依赖关系的要点：

>

spring cloud sleuth otel autoconfigure引入OpenTelemetry instrumentation libs并提供spring自动配置

opentelemetry exporter otlp用于向apm服务器发送数据

      <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

通过这个设置，我成功地在APM中看到了一些数据。示例屏幕：

然而，如果我看看弹性留档，我看到他们的屏幕上有额外的数据：痕迹。

对我来说，它看起来缺少span和事务名称（我只看到HTTP GET而不是名称），至少它们存在于留档映像中。

有人知道为什么会发生这种情况以及如何解决吗？

这是弹性中的示例跟踪文档：
