Description: &Default warning threshold, in megabytes, for the size of associated shared memory segment monitoring of the shared memory watcher to add. The active warning threshold is derived from this value and represents a rising threshold. The derived value must be greater than 0.0, less than or equal to the total value (maximum capacity) of the monitored resource as specified in uxsA2StatusSHMSegSzTotal, but cannot be greater than the active critical threshold. These constraints will be maintained by the agent during all configuration actions. The threshold can be specified as either an absolute value (n) or a percentage (n%). It can also be specified as the absolute value left free (nF). The value of uxsA2StatusSHMSegSzTotal will be the reference value for n% and nF notations.
