How to View the Data that Configures Available Capacity in PowerFlex Manager

hello.
I would like to know how to view the data that makes up the Usable Capacity within the Dashboard of PowerFlex Manager.

The following values exist in the UI, each showing both total and per base capacity.
- Physical net
- System
- Free capacity
- Total capacity

Q. If all of the above values are queried using the REST API in the link below, please tell me what label each value corresponds to in the response. (There are more than 2 bases)

Specifically, I'm interested in the labels of the response values that correspond to the values below.
- Physical net (total)
- Physical net (base 1)
- Physical net (base 2)
- System (total)
- System (base 1)
- System (base 2)
- Free capacity (total)
- Free capacity (base 1)
- Free capacity (base 2)
- Total capacity (total)
- Total capacity (base 1)
- Total capacity (base 2)

Thank you.
