Power BI Premium Performance Monitoring

I have a Power BI Premium instance, and would like to monitor the performance to know if I need to upgrade the size and also to know how much usage the machine is getting (views, etc).  

I found the "Power BI Usage Metrics" view, but it has two limitations that I am trying to overcome.  First, I am running this in a multi-tenant setup, where each tenant has their own workspace, and the usage metrics seem to be limited to a single workspace.  I would like a similar report for all workspaces (preferably with the color legend being workspace!).

Second, I can't see any way to look at how the Power BI Premium server itself is doing.  We are slowly turning on additional customers, but I can't tell how to see if we are overloading the current server.  Is there a way to monitor this?
