This object determines the type of log messages that will be saved to non-volatile storage when they occur. Messages are classified based on their type. Selecting a type value causes all log messages that have an associated value less than or equal to the type value specified to be saved when the log message is entered into the system. For example, specifying the value msgTypeCritical(1) causes only messages classified as 'critical' to be saved to non-volatile storage. Specifying msgTypeSerious(2) causes 'critical' and 'serious' messages to be saved. Specifying msgTypeNone(4) causes no messages to be saved. Note that non-volatile storage space is quite limited in many systems such that the user should exercise caution when specifying the type of log messages that are to be saved in non-volatile storage. Messages are no longer saved in non-volatile storage when this space is exhausted. A log message is automatically generated to alert the user of this situation.
