Chapter 12 Logging
Setting the Log Level
Log levels determine the amount of information delivered in a log. Logs can have
one of five levels of detail. A detailed log-level setting creates larger log files and
has a greater impact on system performance than an abbreviated log-level setting.
A detailed log-level setting includes all the messages contained in the abbreviated
log-level settings, plus additional messages. As the level of detail increases,
system performance decreases.

Note
You can specify different logging levels for each log type.

Log Level
Description
Critical
Only errors are logged. This is the most abbreviated log-level
setting. At this log level, you cannot monitor performance and
important appliance activities; however, the log files do not reach
maximum size as quickly as they do at a detailed log level. This
log level is analogous to the syslog level Alert.

important appliance activities; however, the log files do not reach
maximum size as quickly as they do at a detailed log level. This
log level is analogous to the syslog level Alert.
Warning
All system errors and warnings are logged. At this log level, you
cannot monitor performance and important appliance activities.
The log files reach maximum size more quickly than they do at
the Critical log level. This log level is analogous to the syslog
level Warning.

Information
Second-by-second operations of the system are logged. For
example, connections opened and delivery attempts are logged.
The Information level is the recommended setting for logs. This
log level is analogous to the syslog level Info.

Debug
More detailed information is logged than at the Information log
level. Use the Debug log level when you are troubleshooting an
error. Use this setting temporarily, and then return to the default
level. This log level is analogous to the syslog level Debug.

Trace
All available information is logged. The Trace log level is
recommended only for developers. Using this level causes a
serious degradation of system performance and is not
recommended. This log level is analogous to the syslog level
Debug.
