The cloud log module of IoT Hub provides a comprehensive, stable, and reliable log service that logs information in multiple dimensions such as device behavior, message content, and device exception. You can search for key device logs by time, log type, result, device name,
RequestID, and keyword to identify and troubleshoot business issues easily.
Running logs are divided into behavior logs, content logs, and device logs. You can search for logs by time and keyword.
You can search for logs of all communication behaviors between a device and the cloud, including device connection, disconnection, publishing, and subscribing.
You can search for detailed logs of communication content between a device and the cloud.
Device logs display device information at four levels: ERROR, WARN, INFO, and DEBUG. You can enable/configure device log collection on the device details page.
A cloud log loads 100 data entries each time. You can click Load More at the bottom of the page to view more log information.
