Figure 21.10 Chart of top visited web domains
Top Requested Web Categories
This chart shows top five web categories requested in the selected period sorted by the
ISS OrangeWeb Filter
module. The number in the chart refers to total number of HTTP
requests included in the particular category. For technical reasons, it is not possible to
recognize whether the number includes requests to a single page or to multiple pages.
Therefore, number of requests is usually much higher than number of visited websites in
the previous chart.
For details on web categories, refer to chapter 12.4 .
Figure 21.11
The chart of top requested web categories
Top 5 users
Top five users, i.e. users with the greatest volume of data transferred in the selected
accounting period.
The chart includes individual users and total volume of transferred data.
The chart shows part of the most active users in the total volume of transferred data in
the selected period. Hover a user’s name in the chart by the mouse pointer to see volume
of data transferred by the user, both in total numbers and both directions (download,
upload).
Click on a user’s name in the chart or in the table to switch to the Individual tab (see
chapter 21.6 ) where statistics for the particular user are shown.
These charts and tables provide useful information on which users use the Internet con-
nection the most and make it possible to set necessary limits and quotas.
Note:
1. Total volume of data transferred by a particular user is a summary of data transferred
by the user from all hosts from which they have connected to the firewall in the
selected period.
2. Data transferred by unauthenticated users is summed and accounted as the not
logged in user. However, this information is not very useful and, therefore, it is
recommended to set firewall to always require authentication. For details, see chap-
