This is the count of currently active faults of this holder's specific type on the local parent object. Because this count is scoped to just one fault category, an admin can use it to see, for example, that a fabric interconnect currently has 2 active connectivity faults without that number being mixed together with unrelated environmental or configuration faults also present on the same device. A total-faults value of 2 on a connectivity-typed holder for Fabric Interconnect A means exactly two connectivity-category faults are currently active there, regardless of how many faults of other types also exist on that switch.
