Reports of Event Logs

The security appliance can perform a rolling analysis of the event logs. The Report
page displays the top 25 most frequently accessed websites, the top 25 users of
bandwidth usage, and the top 25 services that consume the most bandwidth.
Enabling the IP Bandwidth, Service Bandwidth, and TopN Web reports consumes
additional system resources and may impact the system performance. Go to the
Status -> Dashboard page to view the CPU and memory utilization. To conserve
the system resources, disable the reports when they are no longer needed.
To open the Report page, click Status -> Report -> Report.
Click On to enable a report, or click Off to disable a report.
Click Save to save your settings.
If you enable a report, choose this report from the Type drop-down list, the
corresponding statistic information is displayed.
• IP Bandwidth: This report lists the top 25 users of bandwidth usage. It
displays the number of megabytes transmitted per IP address since the
system is up.
• Service Bandwidth: This report lists the top 25 Internet services that
consume the most bandwidth. It displays the number of megabytes
received from the service since the system is up.
This report is helpful to determine whether the services being used are
appropriate for your organization. If the services such as video or push
broadcasts are consuming a large portion of the available bandwidth, you
can block them.

It displays the number of hits to a website since the system is up.
This report ensures that the majority of web access is to appropriate
websites. If inappropriate sites appear in this report, you can block the
websites. For more information on blocking inappropriate websites, see
Configuring the Content Filtering to Control Access to Internet,
page 201, or Web URL Filter, page
