Log files are stored in the /log directory. A variety of subsystems have separate log file entries, including dmesg.
Standard syslog messages go to the user.log file, where log rotation and auto-archive occurs for up to 10 gzipped files:
Show CLI login activity.
[OFOS] more /log/cli.log
Show daily boot messages.
[OFOS] more /log/dmesg
