Chapter 19 Kerio StaR — statistics and reporting
Note: Data in the database used for statistics cannot be removed manually (such action would be meaningless). In statistics, it is possible to switch into another view mode where data is related only to a period we need to be informed about. If you do not wish to keep older data, it is possible to change the statistics storage period (see above).
Requirements of the statistics
The following conditions must be met for correct function of all statistics:
•The firewall should always require user authentication. The statistics by individual users would not match the true state if unauthenticated users are allowed to access the Internet. For details see chapter 8.
•For statistics on visited websites, it is necessary that a corresponding protocol in- spector is applied to any HTTP traffic. This condition is met by default unless special traffic rules disabling the particular protocol inspector are applied (see chapter 23.4).
If the WinRoute proxy server is used, visited pages are monitored by the proxy server itself (see chapter 5.5).
Note: HTTPS traffic is encrypted and, therefore, it is impossible to monitor visited sites and categories. Only volume of transferred data is included in the statistics for such traffic.
•For monitoring of web categories of visited websites, the ISS OrangeWeb Filter mod- ule must be enabled.. In its configuration, the Categorize each page regardless of HTTP rules option should be enabled, otherwise web categories statistics would be unreliable. For details, see chapter 10.4.
19.2 Settings for statistics and quota
Under certain circumstances (too many connected users, great volume of transmitted data, low capacity of the WinRoute host, etc.), viewing of statistics may slow WinRoute and data transmission (Internet connection) down. Be aware of this fact while opening the statistics. Therefore, WinRoute allows such configuration of statistics that is cus- tomized so that only useful data is gathered and useful statistics created. If you do not wish to use statistics, it is possible to disable them (this will increase processor’s performance and save disk space of the WinRoute host).
Statistics and their parameters can be set in the Statistics / Quota tab under Configura- tion → Accounting.
Note: These settings do not affect basic user and interface statistics available in the Administration Console (see chapter 18).
