The following table displays the maximum number of records shown in the report,
the byte count limit, and the hit count limit.
10.5 The Session Monitor Screen
The Session Monitor screen displays information about active sessions for
debugging or statistical analysis. It is not possible to manage sessions in this
screen. The following information is displayed.
• User who started the session
• Protocol or service port used
• Source address
• Destination address
• Number of bytes received (so far)
Amount This field displays how much traffic was sent or received from the
indicated service / port. If the
Direction is Ingress , a red bar is
displayed; if the Direction is Egress , a blue bar is displayed. The unit of
measure is bytes, Kbytes, Mbytes, Gbytes, or Tbytes, depending on the
amount of traffic for the particular protocol or service port. The count
starts over at zero if the number of bytes passes the byte count limit.
See
Table 34 on page 251 .
These fields are available when the Traffic Type is Web Site Hits .
# This field is the rank of each record. The domain names are sorted by
the number of hits.
Web Site This field displays the domain names most often visited. The ZyWALL
counts each page viewed on a Web site as another hit. The maximum
number of domain names in this report is indicated in
Table 34 on page

Hits This field displays how many hits the Web site received. The ZyWALL
counts hits by counting HTTP GET packets. Many Web sites have HTTP
GET references to other Web sites, and the ZyWALL counts these as hits
too. The count starts over at zero if the number of hits passes the hit
count limit. See
