How to monitor the status of IoT Edge Device Offline Mode

Question

Hi Team,

I am checking to see if I can track down the disconnectedness of IoT Edge device from associated IoT HUB using an edge module, can this be doable?

My idea of work is, I am running a DB module on my IoT Edge device, I want to re populate this DB Module, whenever the IoT Edge devices goes disconnected mode (offline mode), can I track this offline mode on my IoT Edge device using any environment variable, if so please guide me how can I do?

Thanks

Hello Dhanavath Vishnu, Thanks for posting the helpful scenario.

I personally like to monitor IoT Devices at scale with provided solution reference, below information may be helpful on the adding metrics-collector module to your deployment and configure it to collect and transport module metrics to Azure Monitor. Please note that there are many other solutions which may be suitable for your scenario, but trying the metrics-collector module may be one of them!!!

Collect and transport metrics

You can remotely monitor your IoT Edge fleet using Azure Monitor and built-in metrics integration. To enable this capability on your device, add the metrics-collector module to your deployment and configure it to collect and transport module metrics to Azure Monitor.

To configure monitoring on your IoT Edge device, follow the Tutorial: Monitor IoT Edge devices.

Hello @Dhanavath Vishnu ,

if you are interested in device connections/disconnections, the device property is not reliable due to various reasons.

Please check out the non-telemetry events outputted by the IoT Hub to routing endpoints:

An alternative you can research is using event grid for monitoring the device connection status.
