Set Severity of Log Information
Syslog is divided into 8 levels according to the Severity (or priority) of the
information. The rule to filter the log information according to the level is: the
more urgent the log information is, the less severe it will be. The log information
with severity higher than the set threshold is forbidden to be output. Only the log
information with severity no higher than this threshold can be output.
Perform the following task in system view.
