By default on Tableau 10.x, the owner of an extract will be notified (via email) if the extract refresh fails.
The Admin View for Extract Refresh and _backgroud_tasks view in the Repository will give you information as to why it failed.
If you want to dig further then using logshark to analyse the backgrounder logs would be your next step.
Hope this helps
we could set up an alert by subscribing.
Henry - If you are the owner of the extract ,by default you should be getting an email .
Please refer to Background extracts to find out more about the error and use logs if necessary also you can use generate snapshot for logs.
Henry, You could alco check a short description why did your extract fail on the Tableau Site if your an admin or site administrator for that particular site where the workbook is. Navigate to Status -> Background Tasks for extracts -> select your extract from the extract drop drown, make sure you change the timeline as it would be set for 24 hrs. If your extract failed within 24hrs then it wouldn't show anything. just hover on the extract which failed(red mark) it would display error message.
Hope this works !
Pls attach the error message which can help us to identify the issue.
Check this out.
Publish this on your server with connection to the server postgresql database.
I included hints of fix for each of the failures. We ask all publishers to view this before they ask for admin help.
