Logs
This chapter contains information about configuring general log settings and viewing the
ZyXEL Device’s logs. Refer to the appendix for example log message explanations.
19.1 Logs Overview
The web configurator allows you to choose which categories of events and/or alerts to have
the ZyXEL Device log and then display the logs or have the ZyXEL Device send them to an
administrator (as e-mail) or to a syslog server.
19.1.1 Alerts and Logs
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. 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.
19.2 Viewing the Logs
Click Maintenance > Logs to open the View Log screen. Use the View Log screen to see the
logs for the categories that you selected in the Log Settings screen (see Section 19.3 on page
210 ).
Log entries in red indicate alerts. 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.
