Description: &Default critical threshold, in bytes, for the number of bytes in messages currently outstanding monitoring of any message queue watcher created by the auto watcher. The active critical 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 uxsA2StatusMQCBytesTotal, 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 (n) or a percentage (n%). It can also be specified as the absolute value left free (nF). The value of uxsA2StatusMQCBytesTotal will be the reference value for n% and nF notations.
