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 lter the messages by the severity of the logged event or condition.
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. The table below summarizes the
destinations and defaults for system log messages.
