Table 20-3 Logging Levels
Log Level
Description
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.”
Table 20-4 Log Transfer Protocols
Retrieval Method
Description
FTP on Appliance
(FTP Poll)
This method requires a remote FTP client accessing the appliance to 
retrieve log files using an admin or operator user’s username and 
password. 
When you choose this method, you must enter the maximum number 
of log files to store on the appliance. When the maximum number is 
reached, the system deletes the oldest file. 
This is the default.
