Most frequently, statistic information needed refer to a certain time period (today, last week, etc.). This period is called accounting period.

Accounting period can be set in the toolbar at the top of the Kerio StaR page.

Figure 21.6. Kerio StaR — toolbar and accounting periods

The toolbar includes buttons for fast switching between accounting periods (daily, weekly, monthly). Arrows (previous/next) next to the date (current period) allow fast browsing through the selected period. This browsing is not available for custom accounting periods.

The Custom period option at the top of the statistics page can be used for definition of custom period.

Figure 21.7. Selection of accounting period

Select an item in the Period length combo box (day, week, month). Further options are displayed depending on which option has been selected.

Note: Weeks and months might not correspond with weeks and months of the civil calendar. In configuration of statistics (see chapter 21.2  Settings for statistics and quota), it is possible to set so called accounting period — starting day of a month and the first day in a week. Changes in these settings affect only new data. The data already having been stored in the database stay the same as before the change.

It is also possible to set a custom accounting period, defined by starting and ending days.

Figure 21.8. Custom accounting period

The starting and ending day can be defined manually or selected from the thumbnail calendar available upon clicking on the icon next to the corresponding textfield.

Note: Under certain circumstances, an information may be reported that this period will be rounded to whole weeks or months. In such a case, the real (rounded) period for the statistics will be set and shown above the Change Period button.

The selected period applies to all tabs until a next selection (or until closing of the Kerio StaR interface). The “today” period is set as default and used upon each startup of the Kerio StaR interface.
