System Log Messages Overview
The JUNOS software processes running on the router generate system log messages (also called syslog 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 login into 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. 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.
