Hi, We are trying to get the moduleI health status using IoTEdgeMetricCollector.For that,I have followed https://learn.microsoft.com/en-us/azure/iot-edge/tutorial-monitor-with-workbooks?view=iotedge-1.4 tutorial to monitor IoT Edge devices .But I am not able view anything on the workbook under Fleet view and Device Details. Tried two methods Send metric direct to Log Analytics as Azure Monitor Send to IoTHub as IoTMessage For both cases logs are coming as Azure Monitor 2.IoT Message When sending as IoT Message,tried to view the data through device explorer but it showing an invalid json I would like to request for a soultion Thanks

Hello. The sent data is in the wrong format for visualization. İnvalid JSON https://learn.microsoft.com/en-us/azure/iot-central/core/troubleshoot-connection Telemetry, property, and command payloads. https://learn.microsoft.com/en-us/azure/iot-central/core/concepts-telemetry-properties-commands

Tried two methods

Send metric direct to Log Analytics as Azure Monitor
Send to IoTHub as IoTMessage

For both cases logs are coming as

Azure Monitor

2.IoT Message

When sending as IoT Message,tried to view the data through device explorer but it showing an invalid json

Hello ,
I have used the both modules "SimulatedTemperatureSensor" and "IoTEdgeMetricsCollector" modules from marketplace as explained in the tutorial. Also verified the simulated data payload is valid. Attaching the payload

{ "machine": { "temperature": 110.4179564495191, "pressure": 11.186855798046478 }, "ambient": { "temperature": 21.090211735847504, "humidity": 24 }, "timeCreated": "2022-09-22T09:10:41.5833677Z" }

Thanks

Device twins are JSON documents that store device state information including metadata, configurations, and conditions. Azure IoT Hub maintains a device twin for each device that you connect to IoT Hub.
