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.
