Gen2 Utilization Metrics Report

Hi, All
I know the Premium Gen2 Utilization Metrics Report is an old report and replaced by the Fabric report.
But im wondering if the Premium Gen2 Utilization Metrics Report is still working, as i get
the following error message sinds last saterday 20 juli 2014.

Data source errorCOM error: mscorlib, The given key was not present in the dictionary.. Table: Detail.

the report was very usefull for me as i used this chart
we had\have a shared capacity with some workspaces.

Based on the utillization i could recharge workspaces by Utillization and operation for each workspace

It is available in Fabric capacity Matrix report?? or in the semantic model?
the old Measures was CPU Time - Total - Spread 

thanks for the help
