Description

🐛 Problem

The possible bug is in Advisor --> workbooks --> Cost Optimization (Preview) workbook --> AHB section -->rate optimization --> AHB.
When looking into VMSS/Windows we can see a dashboard which presents Number of required Cores to enable Windows Azure Hybrid Benefit, which i understand as a total cores that are not currently covered with AHB(Please correct me if im wrong) the number i see is 336.
Below i see another feature which allow me to filter the VM's with AHB and then to download the list:
i download the list, sum all the cores in the list and get 129 total cores. while the dashboard above shows total of 336 vcores.
Where is this inconsistency coming from? seems like a bug..

🤔 Expected

TODO: I would expect to receive the same amounts of cores in both dashboard and the feature under the dashboard.
