To store the log activity in the CSV file formate, I would use the** Denodo Log Custom Wrapper ** available under “**Downloads > Denodo Connects**” section of the Support Site. After downloading, create a base view top of the custom data source in Virtual DataPort. Then use the **Denodo Scheduler**,to export the result periodically in the **CSV** file format. Finally, create a script to automate the uploading of the exported file to Amazon S3 using the Amazon CLI.
For more information, you could refer to the following section,
* [Denodo Log Custom Wrapper - User Manual](https://community.denodo.com/docs/html/document/denodoconnects/8.0/Denodo%20Log%20Custom%20Wrapper%20-%20User%20Manual)
* [Reading the VDP logs with Denodo Log Custom Wrapper](https://community.denodo.com/kb/view/document/Reading%20the%20VDP%20logs%20with%20Denodo%20Log%20Custom%20Wrapper?category=Custom+Elements).
* [Exporters Section](https://community.denodo.com/docs/html/browse/8.0/scheduler/administration/creating_and_scheduling_jobs/configuring_new_jobs/postprocessing_section_exporters).
Hope this helps!
