Configure System Log Messages

The JUNOS software generates system log messages (also called syslog messages) to record events that occur on the routing platform, including the following:

• Routine operations, such as creation of an Open Shortest Path First (OSPF) protocol adjacency or a user login in to the configuration database
• Failure and error conditions, such as failure to access a configuration file or unexpected closure of a connection to a child or peer process
• Emergency or critical conditions, such as routing platform power-down due to excessive temperature

Each system log message identifies the JUNOS software process that generated the message and briefly describes the operation or error that occurred. This manual provides more detailed information about each system log message and, when applicable, describes possible causes of the message and action you can take to correct error conditions. 

NOTE: This version of the JUNOS Internet Software System Log Messages Reference manual documents only some of the JUNOS system log messages. Future revisions of this manual, which generally will be released with new versions of the JUNOS software, will likely include additional messages.

This chapter discusses the following topics:

• System Logging Configuration Statements
• Minimum System Logging Configuration
