Description: &Active critical threshold, in megabytes, as derived from the configured value for the size of associated shared memory segment monitoring of the shared memory watcher. This value represents a rising threshold and 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 less than the active warning threshold. These constraints will be maintained by the agent during all configuration actions.
