Based on what Azure Monitor says the IoT Edge Device is offline when IoTEdgeMetricsCollector module is deployed

Hello,

I'm seeking clarification regarding the functionality of the IoTEdgeMetricsCollector module within an IoT Edge Device. Specifically, I'm interested in how this module helps determine the connectivity status of the IoT Edge Device to the internet or IoT Hub, as well as the connectivity of custom modules to the internet or IoT Hub.

Could someone provide insights or explanations regarding this?

Thank you!

    Hello @Roshan Thomas(UST,IN),

    welcome to this moderated Azure community forum.

    The simple answer is that it does not help to determine that.

    These are two separate mechanisms.

    The MetricsCollector collects Prometheus messages emitted by the edgeAgent and edgeHub modules and sends them to the cloud so the Metrics worksbooks in the IoTHub can read it from Azure Monitoring.

    The connection state is determined at an interval by the IoT Hub. It is seen in the Azure portal UI or you could collect the connectivity events emitted via the routing mechanism.

    Of course, you could combine these two to get more fine-grained insights regarding the connectivity of you could eg. add a heartbeat.
