Connected Device Data provides details about each IoT connected device. The data collected includes information about devices, network requests and error events, and any custom properties and events that you instrument in your IoT application.
This page describes the required field names for Analytics Connected Device data, along with the Events Service internal name. When accessing the data using ADQL queries, you need to use the Events Service internal name in the query. Because IoT Monitoring largely depends on custom data, your connected device Analytics data will most likely include many more field names than given below.
