Logs
17.1 Overview
This chapter contains information about configuring general log settings and viewing the NBG-418N
v2’s logs.
The Web Configurator allows you to look at all of the NBG-418N v2’s logs in one location.
17.2 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.
17.3 View Log Screen
Use the View Log screen to see the logged messages for the NBG-418N v2. 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.
