More detailed settings create larger log files and have a greater impact on 
system performance. More detailed settings include all the messages 
contained in less detailed settings, plus additional messages. As the level of 
detail increases, system performance decreases.

 describes the levels of detail you can choose in the Log Level 

field. 

Critical

This is the least detailed setting. This level only includes errors. 
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.”

Warning

This level includes 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.”

Information

This level includes the detailed system operations. This is the 
default. This log level is equivalent to the syslog level “Info.”

Debug

This level includes data useful for debugging system problems. 
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.”

Trace

This is the most detailed setting. This level includes a complete 
record of system operations and activity. 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.”

Choose how to retrieve the log file from the appliance in the Retrieval Method
