This object is used to control what events will be logged by the event log facility. It is a mask, each bit is used to enable/disable a corresponding set of log messages. The OR2000 uses the standard syslog priorities and facilities. The Mask should only be set to mask specific facilities. The facilities are: LOG_KERN (0<<3) kernel messages LOG_USER (1<<3) random user-level messages LOG_MAIL (2<<3) mail system LOG_DAEMON (3<<3) system daemons LOG_AUTH (4<<3) authorization messages LOG_SYSLOG (5<<3) messages generated internally by syslogd LOG_LPR (6<<3) line printer subsystem LOG_NEWS (7<<3) network news subsystem LOG_UUCP (8<<3) UUCP subsystem LOG_CRON (9<<3) clock daemon LOG_AUTHPRIV (10<<3) authorization messages (private) LOG_FTP (11<<3) ftp daemon LOG_NTP (12<<3) NTP subsystem LOG_SECURITY (13<<3) security subsystems (firewalling, etc.) LOG_CONSOLE (14<<3) /dev/console output - other codes through 15 reserved for system use LOG_LOCAL0 (16<<3) reserved for local use LOG_LOCAL1 (17<<3) reserved for local use LOG_LOCAL2 (18<<3) reserved for local use LOG_LOCAL3 (19<<3) reserved for local use LOG_LOCAL4 (20<<3) reserved for local use LOG_LOCAL5 (21<<3) reserved for local use LOG_LOCAL6 (22<<3) reserved for local use LOG_LOCAL7 (23<<3) reserved for local use On the BG2000: Each nibble (4 bits == 1 hex digit == a nibble) represents a category of log messages. There are 4 levels of messages per category (1 bit per level per category). The least significant bit is a higher priority message. As follows: security - nibble 1, bits 1-4 errors - nibble 2, bits 5-8 system startup - nibble 3, bits 9-12 warnings - nibble 4, bits 13-16 information - nibble 5, bits 17-20 0x00000 - No events will be logged. 0x000F0 - Only errors will be logged. 0x0F0F0 - Warnings and errors will be logged. 0xFFFFF - All events will be logged.
