Aws x 射线不适用于 fargate 上的边车容器

Question

我尝试在 fargatge 上设置 aws x-ray。但是没有错误，X 光片中也没有出现指标。这是我对 Fargate 的任务定义的一部分。我尝试调试潜在问题，但在使用 docker compose 和 x-ray 守护程序的本地机器上它可以工作，这表明应用程序配置正确。

demoRole - 拥有对 xray 的完全访问权限

安全组 - 在 TCP 80,2000 和 UDP 2000 上向全世界开放

在那个特定的任务定义中，我添加了环境变量。但删除它们不会改变任何事情。

这些是来自两个容器的日志：

在其他测试中，我尝试为 X 射线设置单独的任务，但仍然无法正常工作。有什么我想念的吗？

您能否在您正在检测的服务上启用 X-Ray SDK 的调试模式？看起来配置是正确的，可能是您的仪器设置有问题。这将启用额外的日志，以便我们诊断问题。
