CHAPTER 32 Logs Screens 32.1 Overview In the log screens you can configure general log settings and view the ZyWALL's logs. The logs cover categories such as 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. 32.1.1 What You Can Do in the Log Screens • Use the View Log screen (Section 32.2 on page 555) to see the logs for the categories that you selected in the Log Settings screen. • Use the Log Settings screen (Section 32.3 on page 558) to configure to where the ZyWALL is to send logs; the schedule for when the ZyWALL is to send the logs and which logs and/or immediate alerts the ZyWALL is to send. 32.1.2 What You Need To Know About Logs 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 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. Finding Out More Refer to Section 32.4 on page 561 for log message explanations. 32.2 The View Log Screen The web configurator allows you to look at all of the ZyWALL's logs in one location. Click 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 32.3 on page 558). When the log is full it will begin to delete older entries as it adds new ones. You can configure the ZyWALL to email you the log when it is full in the Log Settings screen. Click a column heading to sort the entries by the relevant attribute. A triangle indicates ascending or descending sort order. ZyWALL 5/35/70 Series User's Guide 555
