You are troubleshooting an Azure IoT hub.
You discover that some telemetry messages are dropped before they reach downstream processing.
You suspect that IoT Hub throttling is the root cause.
Which log in the Diagnostics settings of the IoT hub should you use to capture the throttling error events?
When troubleshooting Azure IoT Hub and suspecting throttling issues, you should use the 'DeviceTelemetry' log in the Diagnostics settings. This log captures errors related to the telemetry pipeline, including issues like throttling that occur when sending telemetry events to the IoT Hub. Other logs such as Routes, Connections, and C2DCommands do not specifically capture telemetry-related throttling errors.
