This image shows the Performance Hub screen within DB Management.  The DB shown is the PSFT_PDB_hcmg8f and was linked directly from the APM trace which showed a slow span.
The top of the page allows for quick selection of a time range or any custom time period adn time zone.
Below the selectors is the Activity Summary showing average active sessions in area charts, colored by wait, user I/O, and CPU. There are handles on the horizontal time slider to adjust the time period for analysis.
Below the time slider are tabs for ASH Analytics (shown), SQL Monitoring, ADDM, and Blocking Sessions.
The main panel of the page shows the average active sessions as a load map (or alternatively as line or bar graphs).  The average active sessions can be filtered and be graphed by numerous ASH dimensions. In this image the load map is grouped by Client and Module.  Below the load map are two tabular lists with selectable content. The left table shows SQL ID by wait class, including the SQL plan hash, type and service. The right table shows the User Sessions by wait class, including the username, program and service.
