The least detailed setting. Only errors are logged. Using this setting will not 
allow you to monitor performance and other important activities; however, 
the log files will not reach their maximum size as quickly. This log level is 
equivalent to the syslog level “Alert.”

All errors and warnings created by the system. Using this setting will not 
allow you to monitor performance and other important activities. This log 
level is equivalent to the syslog level “Warning.”

The information setting captures the second-by-second operations of the 
system. For example, connections opened or delivery attempts. The 
Information level is the recommended setting for logs. This log level is 
equivalent to the syslog level “Info.”

Use the Debug log level when you are trying to discover the cause of an error. 
Use this setting temporarily, and then return to the default level. This log level 
is equivalent to the syslog level “Debug.”

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 equivalent to the syslog level “Debug.”
