System Logs Overview
The system logs feature enables you to save the system messages to the log buffer or send them to the
log hosts. The analysis and archiving of the logs can enable you to check the security holes of the
firewall, when and who try to disobey security policies.
System logs are saved on the disk in the format of log files, with the name of sys-date.log. For example,
the system logs on 1st, October, 2007 are saved in file sys-20071001.log. The size of each log file
cannot exceed 300 MB. If the system logs generated in one day are too large, they will be saved in
multiple log files, with the name sys-date.log.n respectively, where a larger value of n indicates that the
logs are generated earlier. The latest system logs in one day are saved in file sys-current.log.
The functions provided by the system log module are listed in the following table:
