This guide is a reference for all log messages generated by NetDefendOS. It is designed to be a
valuable information source for both management and troubleshooting.
1.1. Log Message Structure
All log messages have a common design with attributes that include category, severity and
recommended actions. These attributes enable the easy filtering of log messages, either within
NetDefendOS prior to sending them to a log receiver, or as part of analysis that takes place after
the logging and storage of messages on an external log server.
The following information is provided for each specific log message:
Name
ID
Category
The name of the log message, which is a short string, 1-6 words
separated by _. Please note that the name cannot be used as a
unique identification of the log message, as several log messages
might share the same name.
The ID is a number made up of a string of 8 digits which uniquely
identifies the log message. The first 3 digits identify the category to
which the log message belongs.
Note
In this guide, the Name and the ID of the log message
form the title of the section describing the log message.
Log messages are grouped into categories, where each category
maps to a specific subsystem in NetDefendOS. For instance, the
IPSEC category includes some hundreds of log messages, all related
to IPSec VPN activities. Other examples of categories include ARP,
DHCP, IGMP and USERAUTH.
In this guide, categories are listed as sections in Chapter 2, Log
