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.
19.2 Wha t You Ne e d 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 Syste m Errors consist of both logs and alerts. You
may differentiate them by their color in the Vie w 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
Sc he dule ). Selecting many alert and/or log categories (especially Ac c e ss Control) may result in many e-
mails being sent.
