I know nothing about this so I ran a test and here's what I found out...
The http_req table is the one where the information can be found.
You want to look in the ACTION column where the value is "vud".
The CURRENTSHEET column is the workbook/sheet name in the database format, not in the human-readable format! For example, I used the workbook "tabbed admin views" and the sheet "Traffic to Views", thus the CURRENTSHEET value for me was "tabbedadminviews/TraffictoViews".
The column HTTP_REQUEST_URI tells you the request made and it's the last values that tell you if it's a summary or detail download:
~ if the field ends with "csv=true&summary=true" then the user downloaded the data in summary form
~ if the field ends with "csv=true" then the user downloaded the data in detailed form.
Here's what it looks like when I filtered the data for today only and only looking at my IP address (filtered on REMOTE_IP):
Read from the bottom and work your way up.
(1) is the call for Summary download
(2) is the call for Detailed download
You want to know the SITE_ID so you don't get workbooks confused if you have more than one Site. However, this isn't a guarantee that you'll know the exact workbook if Users duplicate workbook and/or sheet names (this is NOT uncommon ) so you can parse the HTTP_REFERER field to pull out that data. Here's an example of that column from my data:
If you study the data in the field you'll find:
~ the Site: /t/area51
~ the Workbook: /w/tabbedadminviews
~ the Sheet (a.k.a. View): /v/TraffictoViews
This is the hard part and will get you started. This is not a guarantee that this is 100% accurate and it has not been thoroughly vetted.
Thank you so much for your reply!
Thanks for taking time and replying me. I'll check it out.
Thank you for the detailed investigation Toby. A remarkable Ambassador!!!
Just a short follow-up (reading from the bottom up): I opened a workbook, went to a sheet, downloaded it as a PDF (opened in Adobe Reader) and then immediately downloaded it as a Tableau workbook (opened in Tableau Desktop). This shows what the ACTION, CONTROLLER, and HTTP_REQUEST_URI fields look like.
(1) Downloading a viz as a PDF.
(2) Downloading a viz as a Tableau workbook.
