Syslog messages are prioritized by a combination of facility and urgency level:
- there are 10 standard facilities and 8 that can be configured for your use. These are monitored by ENA syslogger:
Facility Description kern kernel messages. user user-level messages. mail subsystem. daemon system daemons. auth security/authorization messages. syslog internally generated syslogd messages. news usenet news subsystem. uucp Unix to Unix Copy Program subsystem. cron clock daemon. local0 reserved for local use. local1 reserved for local use. local2 reserved for local use. local3 reserved for local use. local4 reserved for local use. local5 reserved for local use. local6 reserved for local use. local7 reserved for local use.
- The urgency levels are listed in order below. When you specify a level in entuity.cfg, you are selecting that level and all the levels above it.
Level Level Name Description 0 emerg system is unusable. 1 alert immediate action required 2 crit critical condition. 3 err error condition. 4 warning warning condition. 5 notice normal but significant condition. 6 info informational. 7 debug debugging messages.
Through the syslogger section in entuity.cfg, you can set the combination of facility source and urgency level that syslogger accepts.
