J-series Services Routers support configuring and monitoring of system log messages
(also called syslog messages). You can configure files to log system messages and
also assign attributes, such as severity levels, to messages. The View Events page on
the J-Web interface enables you to filter and view system log messages.
This chapter contains the following topics. For more information about system log
messages, see the JUNOS System Log Messages Reference.
If the router is operating in a Common Criteria environment, see the Secure
Configuration Guide for Common Criteria and JUNOS-FIPS.
