This is the defaultThresholdsAdded property of a stats ThresholdPolicy object, a TruthValue flag indicating whether UCS Manager has already populated this policy with Cisco's default set of threshold definitions. An admin checks this flag to know whether a threshold policy still needs the standard baseline thresholds applied, or whether it already has them and any changes seen are custom additions on top. For example, a newly created threshold policy showing defaultThresholdsAdded as false tells the admin no thresholds will fire yet until either the defaults are added or custom ones are defined.
