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 38.)
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 37 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 38 lists the severity levels and their descriptions. (For defaults, see Table 37.)
