System Log Facilities and Severity Levels
When specifying the destination for system log messages, you
can specify the class (facility) of messages to log and the minimum
severity level (level) of the message for each location.
Each system log message belongs to a facility, which is a group
of messages that are either generated by the same software process
or concern a similar condition or activity.
Table 161 lists the system
logging facilities, and Table 162 lists the system logging severity levels. For more information about
system log messages, see the JUNOS System Log Messages Reference.
