Capsule storage info (or other facts)

Rich J or someone else on the Satellite side
Is the source of information for the "Pulp storage" and "Mongo Storage" on the Capsule info page in the UI exposed via API?
Couldn't find it in facts for the host, or in the capsule information.

Trying to create a single-pane view of Satellite environment health, and this would be helpful for viewing storage (or any other facts that might be exposed.

Thanks!
