This chapter contains information about the ZyWALL’s system and threat reports.
29.1 Configuring Reports
The System Reports screens display statistics about the network usage of the LAN, DMZ or
WLAN computers. The Threat Reports screens display IDP, anti-virus and anti-spam
statistics.
29.2 System Reports Screen
Click REPORTS > SYSTEM REPORTS to display the following screen.
The System Reports screen displays which computers on the LAN send and receive the most
traffic, what kinds of traffic are used the most and which web sites are visited the most often.
The ZyWALL can record and display the following network usage details:
• Web sites visited the most often
• Number of times the most visited web sites were visited
• The most-used protocols or service ports
• The amount of traffic for the most used protocols or service ports
• The LAN, DMZ or WLAN IP addresses to and/or from which the most traffic has been
sent
• How much traffic has been sent to and from the LAN, DMZ or WLAN IP addresses to
and/or from which the most traffic has been sent
Note: The web site hit count may not be 100% accurate because sometimes when an
individual web page loads, it may contain references to other web sites that
also get counted as hits.
The ZyWALL records web site hits by counting the HTTP GET packets. Many web sites
include HTTP GET references to other web sites and the ZyWALL may count these as hits,
thus the web hit count is not (yet) 100% accurate.
