The settings in the six directions are independent from each other. The settings will
take effect only after enabling the information center.
3 Define the log filtering rules
The SYSLOG classifies the information into 8 severity or urgent levels. The log
filtering rule is that the system prohibits outputting the information whose severity
level is greater than the set threshold. The more urgent the logging packet is, the
smaller its severity level is. The level represented by "emergencies" is 0, and that
represented by"debugging" is 7. Therefore, when the threshold of the severity
level is "debugging", the system will output all the information.
