Monitoring Events and Managing System Log Files

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.

Before configuring and monitoring system log messages on Services Routers, become familiar with the terms defined in Table 80 on page 155.

Table 80: System Log Message Terms

Term	Definition
event	Condition that occurs on a Services Router at a particular time. An event can include routine,
	failure, error, emergency or critical conditions.
event ID	System log message code that uniquely identifies a system log message. The code begins with
	a prefix indicating the software process or library that generates the event.
facility	Group of messages that either are generated by the same software process (such as accounting
	statistics) or concern a similar condition or activity (such as authentication attempts). For a list
	of system logging facilities, see Table 81 on page 157.
