On the invoices include the costs of data-transfer based on capacity units / hour. Capacity units are calculated based on 3 categories: "New connections or flows","Active connections or flows" or "Processed bytes".
One of the difficulties from the user perspective is to understand how much is the usage of our application on MongoDB is contributing for each category?

Example: I was charged for 10000 Capacity Units for 3h, at $0.012 hour. Final charge is 360$. The problem with this is that I don't know what is contributing most for my cost, is it the "New connections"? "Active Connections? or "Processed Bytes"?
