System Log Messages Overview
The JUNOS software generates system log messages to record events that occur on the router, including the following:
- Routine operations, such as creation of an Open Shortest Path First (OSPF) protocol adjacency, or a user logging 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 router power-down due to excessive temperature
Each system log message identifies the software process that generated the message and briefly describes the operation or error that occurred.
The chapter discusses the following topics:
- System Logging Configuration Guidelines
- Minimum System Logging Configuration
- Configure System Logging
- Direct Messages to a Log File
- Direct Messages to a User Terminal
- Direct Messages to the Console
- Archive System Logs
- Direct Messages to a Remote Machine
