Description: &Default critical threshold, in kilobytes, for the delta size utilization monitoring of the directory watcher to add. The active critical threshold is derived from this value and represents a rising threshold. The derived value must be greater than 0.0, but cannot be less than the active warning threshold. These constraints will be maintained by the agent during all configuration actions. The threshold can be specified as either an absolute value or a percentage and can denote a growth, shrinkage or change in either direction: Absolute shrinkage (n-), absolute growth (n+), absolute change in either direction (n), percentage shrinkage (n%-), percentage growth (n%+), or percentage change in either direction (n%). The value of uxsA2StatusDirSizeTotal will be the reference value for n% notations.
