This document describes how to export service logs through the API Gateway console for data analysis and problem location.
Directions

3. Click the Service Log tab.
4. Click the Export icon in the red box as shown in the following figure to export service logs.
Note:
The time range of the logs to be exported is consistent with the time range of the queried logs. You can modify the time range of the logs to be exported by modifying the time range of the queried logs.
