Using DPA to report on DP Suite license capacities

Has anyone tried to use DPA to report on DP Suite license capacities?

My environment has NetWorker, Avamar, and Data Domain in a bi-directional replicated configuration. No tape, all disk.

When I run the DPA NetWorker License Compliance Report and choose the NetWorker server as the source, I get no output whatsoever. If I run a License Detail Report, all I get is info about having "1 instance" and nothing about capacity whatsoever.

Am I overthinking things by trying to get the NetWorker used capacity info separately? If the NetWorker data is stored on the Data Domain, and all data (Avamar, NetWorker, and DD FS data) is replicated between the Data Domains, is the current total used capacity of the DD effectively how much of the license is being used?

All comments/feedback appreciated - thanks.
