This object defines the reaction threshold types.
invalid(0): Invalid value.
average(1): If reaction threshold type is average and the average
value of watched operation exceeds threshold limit,
an action specified in hwNqaReactActionType is
generated when hwNqaReactCurrentStatus changes.
consecutive(2): If reaction threshold type is consecutive and
the times of watched operation consecutively exceeds
the limit specified by hwNqaReactThresholdConsecNum,
an action specified in hwNqaReactActionType is
generated when hwNqaReactCurrentStatus changes.
accumulative(3): If reaction threshold type is accumulative and
the times of watched operation accumulatively exceeds
the limit specified by hwNqaReactThresholdAccumNum,
an action specified in hwNqaReactActionType is
generated when hwNqaReactCurrentStatus changes.
If reaction threshold type is not configured, the value of this
object is 'invalid'.
