What is the purpose of xyz.openbmc_project.Inventory.Item.Global interface and getGlobalPath in HealthPopulate ?

Hi all,

I would like to set the Status/Health of a target directly that target is not a sensor.

I saw HealthPopulate, composed of 2 parts:

  *   getAllStatusAssociations like all_sensors => linked to a rela sensor => not interested
  *   getGlobalPath => cannot understand how it works ? Should I add this interface to a dbus object, and the magic appears ?

I would be grateful if you have any example !

I apologize for my French, do not hesitate to ask me if my question is not understandable,

Kind Regards,

As I understand it, Inventory.Item.Global is a way to designate what 
resources should have the Redfish health rollup from their children.

Inventory Items like Chassis or System would be good candidates for this 
Inventory.Item.Global interface. An example is a Redfish Chassis with 
Health Rollup from children resources like power supplies and fans.
