AWS IoT Device Management 已将 MQTT 会话数据添加到连接状态 API,使您能够排查连接问题并审计物联网(IoT)设备机群的连接模式。

此次发布将 AWS IoT Device Management 现有的连接状态 API 与 AWS IoT Core 新推出的 GetConnection API 实现完全对等,使您能够通过 IoT 设备的事物名称检索详细的连接信息和 MQTT 会话信息。除了已有的连接状态、时间戳和断开连接原因之外,您现在还可以查看 MQTT 会话超时和会话到期值,以及可选的套接字级别详细信息,例如源和目标 IP 地址、端口以及客户端 VPC 端点 ID。对套接字信息的访问权限是通过精细 IAM 策略控制的,因此您可以仅向有需要的团队授予该访问权限。

相较于 AWS IoT Core 的 GetConnection API,连接状态 API 的一项关键优势是数据留存。GetConnection API 在设备断开连接后会将连接和会话详细信息保留 30 分钟,而连接状态 API 则会无限期存储这些信息。这意味着,即便设备已离线很长时间,您仍能调查断开连接的原因、查看会话元数据并排查问题。

这项增强功能已在支持 AWS IoT Device Management 的所有 AWS 区域推出。AWS IoT Device Management 仅支持已在 AWS IoT Core 事务注册表中注册的设备。要了解更多信息,请访问 AWS IoT Device Management 文档参考指南。
