Explanation

The device telemetry category tracks errors that occur at the IoT hub and are related to the telemetry pipeline. This category includes errors that occur when sending telemetry events (such as throttling) and receiving telemetry events (such as unauthorized reader). This category cannot catch errors caused by code running on the device itself. Note: The metric d2c.telemetry.ingress.sendThrottle is the number of throttling errors due to device throughput throttles. https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-monitor-resource-health
