syslog Paramaters - per [RFC3164]
The syslog protocol utilizes numerical facility and severity values.
The IANA lists those that have been noted below.
(created 2001 August 21)
syslog Message Facilities
-------------------------
Numerical
Code Faciltiy Reference
--------- -------- ---------
0 kernel messages [RFC3164]
1 user-level messages [RFC3164]
2 mail system [RFC3164]
3 system daemons [RFC3164]
4 security/authorization messages (note 1) [RFC3164]
5 messages generated internally by syslogd [RFC3164]
6 line printer subsystem [RFC3164]
7 network news subsystem [RFC3164]
8 UUCP subsystem [RFC3164]
9 clock daemon (note 2) [RFC3164]
10 security/authorization messages (note 1) [RFC3164]
11 FTP daemon [RFC3164]
12 NTP subsystem [RFC3164]
13 log audit (note 1) [RFC3164]
14 log alert (note 1) [RFC3164]
15 clock daemon (note 2) [RFC3164]
16 local use 0 (local0) [RFC3164]
17 local use 1 (local1) [RFC3164]
18 local use 2 (local2) [RFC3164]
19 local use 3 (local3) [RFC3164]
20 local use 4 (local4) [RFC3164]
21 local use 5 (local5) [RFC3164]
22 local use 6 (local6) [RFC3164]
23 local use 7 (local7) [RFC3164]
Note 1 - Various operating systems have been found to utilize
Facilities 4, 10, 13 and 14 for security/authorization,
audit, and alert messages which seem to be similar.
Note 2 - Various operating systems have been found to utilize
both Facilities 9 and 15 for clock (cron/at) messages.
syslog Message Severities
-------------------------
Numerical
Code Severity Reference
--------- -------- ---------
0 Emergency: system is unusable [RFC3164]
1 Alert: action must be taken immediately [RFC3164]
2 Critical: critical conditions [RFC3164]
3 Error: error conditions [RFC3164]
4 Warning: warning conditions [RFC3164]
5 Notice: normal but significant condition [RFC3164]
6 Informational: informational messages [RFC3164]
7 Debug: debug-level messages [RFC3164]
