Log message components
Each log message contains the following components:
Logging destinations and levels
A logging destination is the location to which logged event messages are sent for storage or display. By default, only
session logging is disabled. You can enable or disable logging to each destination and filter the messages by the severity
of the logged event or condition. (For details, see Table 48: “Event severity levels” on page 771.)
System events and conditions at different severity levels can be logged to multiple destinations. By default, events at the
error level and higher are posted to the console and to the log buffer. Debug output is logged to the trace buffer by
default. Table 47 summarizes the destinations and defaults for system log messages.
Specifying a severity level sends log messages for events or conditions at that level or higher to the logging destination.
Table 48 lists the severity levels and their descriptions. (For defaults, see Table 47: “System log destinations and
defaults” on page 770.)
