location.
16.2
What You Need to Know
An alert is a type of log that warrants more serious attention. They include system
errors, attacks (access control) and attempted access to blocked web sites or web
sites with restricted web features such as cookies, active X and so on. Some
categories such as
System Errors
consist of both logs and alerts. You may
differentiate them by their color in the
View Log
screen. Alerts display in red and
logs display in black.
Alerts are e-mailed as soon as they happen. Logs may be e-mailed as soon as the
log is full (see
Log Schedule
). Selecting many alert and/or log categories
(especially
Access Control
) may result in many e-mails being sent.
16.3
View Log Screen
Use the
View Log
screen to see the logged messages for the NBG-416N. Options
include logs about system maintenance, system errors, access control, allowed or
blocked web sites, blocked web features (such as ActiveX controls, Java and
cookies), attacks (such as DoS) and IPSec.
Log entries in red indicate system error logs. The log wraps around and deletes
the old entries after it fills. Click a column heading to sort the entries. A triangle
indicates ascending or descending sort order.
