It is not possible to run an Ad Hoc report for an Interface using the "UIM Metrics Topic"
Steps to Reproduce:
1- Login to UMP, create an Interface group
2- Create a filter for interfaces to appear in the group
3- Login to CABI and try to create an Ad Hoc report using the
topic: "UIM Metrics Topic"
Problem: If you select an interface group, you cannot select any devices or metrics.
The fix for the CABI content to allow us to run reports on Interfaces will
be available in next major release of CABI. It would be along with 9.0.2 release. So, the ETA is FY19Q3.
