Kerio StaR — statistics and reporting
The WinRoute’s web interface provides detailed statistics on users, volume of transferred data,
visited websites and web categories. This information may help figure out browsing activities
and habits of individual users.
The statistics monitor the traffic between the local network and the Internet. Volumes of data
transferred between local hosts and visited web pages located on local servers are not included
in the statistics (also for technical reasons).
One of the benefits of web statistics and reports is their high availability. The user (usually an
office manager) does not need the Administration Console and they even do not need WinRoute
administrator rights (special rights are used for statistics). Statistics viewed in web browsers
can also be easily printed or saved on the disk as web pages.
Note:
1.
The WinRoute administrator should inform users that their browsing activities are moni-
tored by the firewall.
2.
Statistics and reports in WinRoute should be used for reference only. It is highly unrecom-
mended to use them for example to figure out exact numbers of Internet connection costs
per user.
3.
For correct functionality of the Kerio StaR interface, it is necessary that the WinRoute
host’s operating system supports all languages that would be used in the Kerio StaR in-
terface. Some languages (Chinese, Japonese, etc.) may require installation of supportive
files. For details, refer to documents regarding the corresponding operating system.
21.1 Monitoring and storage of statistic data
Diverse data is needed to be gathered for the statistics. Statistic data is stored in the data-
base (the star\data subdirectory of the WinRoute’s installation directory — for details, see
chapter
). Total period length for which WinRoute keeps the statistics can be set in the
Accounting section of the Administration Console (see chapter
). By default, this time is
set to 24 months (i.e. 2 years).
For technical reasons, the WinRoute Firewall Engine stores gathered statistic data in the cache
(the star\cache subdirectory) and data is recorded in the database once per hour. The cache
is represented by several files on the disk. This implies that any data is kept in the cache even
if the WinRoute Firewall Engine is stopped or another problem occurs (failure of power supply,
etc.) though not having been stored in the database yet.
