如何使模块之间的 IoT Edge 消息路由在 arm32 (Raspberry Pi) 上工作

【问题标题】：How to make Iot Edge message routing between modules work on arm32 (Raspberry Pi)如何使模块之间的 IoT Edge 消息路由在 arm32 (Raspberry Pi) 上工作
【发布时间】：2018-12-21 16:01:20
【问题描述】：

我使用 Visual Studio Code 通过 View -> Command Palette... -> AzureIotEdge:NewIoTEdgeSolution 使用 C# 模块 模块模板创建了一个 IoT Edge 解决方案。这会生成一个带有两个模块的 IoT Edge 解决方案：tempSensor 使用虚拟遥测数据创建消息，而 SampleModule 应该接收这些消息，打印它们，然后将它们传递给 IotHub .

我为 arm32 构建解决方案并将其部署到 Rasperry Pi（运行最新的 Raspbian）。这些模块随后显示为在设备上运行，但如果我监控 d2c 消息，则没有任何模块到达 IoT 中心。

如果我在设备上运行 sudo iotedge logs tempSensor -f，我可以看到正在生成消息。

如果我运行 sudo iotedge logs SampleModule -f，我只会看到 IoT Hub 模块客户端已初始化。 它记录在 Init() 方法中。 PipeMessage 方法没有日志记录，似乎根本无法访问。

如果我为 amd64 构建解决方案并将其部署到虚拟机，一切都会按预期工作。

有没有办法让它在运行 Raspian 的 Raspberry Pi 上运行？

顺便说一句：我也尝试了 Azure Functions C# 模块模板。结果相同：在 amd64 上可以工作，但在 arm32 上不行。

更新： 以下是 edgeAgent 的日志记录：

所以问题是由 System.OutOfMemoryExceptions 引起的。但是是什么导致了这些异常？

Update2：这似乎是一个已知问题（请参阅here），可以通过将 OptimizeForPerformance 设置为 false 来解决。我会试试这个，看看它是否有效。

【问题讨论】：

  • 可以分享一下edgeHub和edgeAgent（sudo iotedge logs &lt;module name&gt;）的日志吗？
  • 我添加了上面的日志。 edgeHub中有很多System.OutOfMemoryExceptions。知道是什么导致了异常吗？
  • @LazarusX 感谢请求 edgeHub 模块的日志。这让我找到了正确的方向。

标签： raspberry-pi azure-iot-edge


【解决方案1】：

由于 edgeHub 模块中的 System.OutOfMemoryExceptions，模块之间的消息路由不起作用。问题描述和讨论here。

微软已经实施了一个解决方案，描述为here。

简而言之：如果在 Raspberry Pi 上运行 IotEdge 解决方案，则必须将环境变量 OptimizeForPerformance 设置为 false。

【讨论】：

  • 来自 Azure 文档：“不要针对受限设备上的性能进行优化 IoT Edge 中心默认针对性能进行了优化，因此它会尝试分配大块内存。此配置可能会导致稳定性问题较小的设备，例如 Raspberry Pi。如果要部署资源受限的设备，您可能需要在 IoT Edge 集线器上将 OptimizeForPerformance 环境变量设置为 false。
【解决方案2】：

似乎与 https://docs.microsoft.com/en-us/azure/iot-edge/troubleshoot#stability-issues-on-resource-constrained-devices

请参考链接并在部署清单中关闭 OptimizeForPerformance。

【讨论】：

  • 我自己刚刚发现并在同一时间发布了答案 :-) 不过我会接受你的答案。
