This is the human-readable description of what this state machine is currently doing, mirrored from the FSM object's own current-stage text. Because removing a QoS definition touches multiple fabric interconnects asynchronously, UCS Manager models the whole deletion as a state machine, and this object is the FSM's own top-level status record. A live example would read 'Applying egress QoS configuration on Fabric Interconnect B', updating each time the workflow advances to a new stage.
