Slices

Purpose

Slices are used for building the statistic reports for separate users groups. Building of a slice is performed in several steps.

Here is an example, explaining the difference between filters and slices.

The field "Referrer" should contain the value "Google".

All requests containing the referrer with the substring "google" will be picked out by the filter. Upon using the filter, all the subsequent requests in the reports will be discarded; the reports "Pageviews per User", "Pageviews per Host", "Visitors Paths" will function incorrectly, because information of all the users requests is required for their building.

The table below illustrates the situation in details:

Request ID

User ID

Referrers

Pages

1

After the filter has been applied, only one request will be left:

Request ID

User ID

Referrers

Pages

http://www.google.ru/search?hl=ru&q=site+statistics&lr=

Unlike the filter, after the slice has been applied, all requests from the user 1 will be left:

Request ID

User ID

Referrers

Thus, when using the filter, the depth will be of 1 page, which is incorrect. When using the slice, the result is correct - 4 pages.

To create a slice, you should select a filter as a basis at the drop-down menu of "Slices" tab. The slice name will be displayed at the "Slices" tab. Time period of the building process is indicated for each slice. If time period is changed, then the slice is rebuilt automatically.
