The over-the-air (OTA) update feature of IoT Platform provides statistics. On the Data analysis tab, you can view statistics on the update package versions of a product and the success rate of each update batch. This helps you analyze why an OTA update fails and improve the success rate of device updates.

regardless of successful and failed updates, in descending order in a horizontal bar
chart or table. The detailed information includes the source version numbers, update
times, and proportions of update packages.
|Source version upgrade success rate ranking||Based on the Total distribution of source versions section, these two sections display information about update packages by success
or failure rate in descending order in a horizontal bar chart or table. The detailed
information includes the source version numbers, success or failure times, and success
or failure rates of update packages.
If data is displayed in a horizontal bar chart, only the top 5 data is displayed. The average value of the remaining data is calculated and displayed on the Others bar.
