All log files are organized in the log directory (/var/log) according to the facility and priority at which they
have been logged. Remote Syslog sends the requested logs to the remote server(s) at whichever facility and
priority they were initially logged, after filtering the logs based on the selectors configured for the server.
The following log files are setup with the following default selectors:
• syslog catches all logs except daemon.debug, auth or authpriv logs
• daemon.log catches all err level (and above) logs written to the daemon facility
• messages catches all info, notice and warn level logs for all facilities except auth, authpriv, cron, daemon,
mail and news
A selector setup using the following facilities at level info and up is recommended:
• daemon
• user
• kern
• syslog
Diagnostic logs record system information for the purposes of troubleshooting.
