Log Priority
This section provides information on configuring the level of priority log messages are captured 
and corresponding alert messages are sent through e-mail for notification.
Logging Level
The Logging Level control filters events by priority. Events of equal of greater priority are 
passed, and events of lower priority are dropped. The Logging Level menu includes the 
following priority scale items from highest to lowest priority:
  •
Emergency (highest priority)
  •
Alert
  •
Critical
  •
Error
  •
Warning
  •
Notice
  •
Informational
  •
Debug (lowest priority)
Alert Level
The Alert Level control determines how E-mail Alerts are sent. An event of equal or greater 
priority causes an E-mail alert to be issued. Lower priority events do not cause an alert to be 
sent. Events are pre-filtered by the Logging Level control, so if the Logging Level control is 
set to a higher priority than that of the Alert Level control, only alerts at the Logging Level or 
higher are sent. Alert levels include:
  •
None (disables e-mail alerts)
  •
Emergency (highest priority)
  •
Alert
  •
Critical
  •
Error (lowest priority)
Log Redundancy Filter
The Log Redundancy Filter allows you to define the time in seconds that the same attack is 
logged on the Log > View page as a single entry in the SonicWALL log. Various attacks are 
often rapidly repeated, which can quickly fill up a log if each attack is logged. The Log 
Redundancy Filter has a default setting of 60 seconds.
Alert Redundancy Filter
The Alert Redundancy Filter allows you to define the time in seconds that the same attack is 
logged on the Log > View page as a single entry in the SonicWALL log before an alert is issued. 
The Alert Redundancy Filter has a default setting of 900 seconds.
