1.3. Severity levels

1.3. Severity levels
An event has a default severity level, based on how serious the event is. The following eight severity
levels are possible, as defined by the Syslog protocol:
0 - Emergency
1 - Alert
2 - Critical
3 - Error
4 - Warning
5 - Notice
6 - Informational
7 - Debug
Priority in Syslog Messages
In Syslog messages the priority is indicated by the parameter prio=nn.
Excluding Logged Messages
NetDefendOS allows the exclusion from logging of entire catageories of log messages or just
specific log messages. It is also possible to change the severity level of log messages so that a
specific category or a specific message has the severity reset to a particular level when it is sent by
NetDefendOS. These features are documented further in the NetDefendOS Administrators Guide.
