The workbooks that you are interested in creating can be generated using a few data sets:
- Opening the postgres database that's in Tableau (Collect Data with the Tableau Server Repository - Tableau)
- Installing LogShark (Install and Configure Logshark) so it monitors your production system. I'd recommend deploying the reports as well as it already has a lot of the info you are after
- A table of dates for scaffolding (Scaffold data with Tableau Prep to fill gaps in your data set | Tableau Software)
Using these data sources you should have enough data, and sample dashboards, to either give you the reporting you are after or build the reporting that you are after.
