CHAPTER 20
Logs
20.1 Overview
This chapter contains information about configuring general log settings and
viewing the NBG4604’s logs.
The Web Configurator allows you to look at all of the NBG4604’s logs in one
location.
20.2 What You Can Do
•Use the View Log screen (Section 20.4 on page 186) to see the logs for the
categories such as system maintenance, system errors, access control, allowed
or blocked web sites, blocked web features, and so on.
•Use the Log Settings screen (Section 20.5 on page 187) to send copies of the
NBG4604 syslog files to a dedicated syslog server.
20.3 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.
