This object sets the capacity usage percentage, from 10 to 100 and defaulting to 70, at which a previously-raised capacity alarm is cleared, where a value of 10 means the alarm clears once usage drops 10 percentage points below the raise threshold. An admin tunes this to control hysteresis, preventing the alarm from flapping on and off near the raise threshold. For example, with a raise trigger of 80 and this clear trigger left at 70, the alarm would clear only once usage drops to about 70% or below, well under the 80% raise point.
