Interpreting system log messages
Table 6-2 uses the first log message in Figure 6-71 as an example to present the field descriptions:
<189> JAN 01 00:00:58 0.0.0.0-1 TRAPMGR[190295576]: traputil.c(661) 67
%% Cold Start: Unit: 0
Table 6-2. A System Log Message Decomposed
Field Example Description
<189> The leftmost column displays a combination of the facility and the severity. Divide
the number in angle brackets by 8 to arrive at the facility. The remainder is the
severity (per RFC 3164). In this example, the <189> displayed in the leftmost column
divided by 8 yields a remainder/severity of 5.
If you do not set the facility option, the severity levels display clearly in that field:
• 0 = emergency
• 1 = alert
• 2 = critical
• 3 = error
• 4 = warning
• 5 = notice
• 6 = informational
• 7 = debug
