Report Groups

An event can be associated with one or more report groups. A report group is a set of dimensions that can be displayed on the same report. A report group can be thought of as the parent of dimensions.

Example report group

For example, you can create a report group that is called user agent properties to contain values for the following properties that are associated with mobile user agents:

  • User agent name
  • Screen width
  • Screen height
  • Javascript support

In this example, the inclusion of the user agent name dimension is useful for combining dimensions into new reports. If another dimension also includes this dimension, then dimensions from each of the two dimensions can be displayed in the same report.

These dimensions are of different data types, yet they can be added to the same report in the Discover Report Builder.

Up to a maximum of 4 dimensions can be displayed in the same report group. Dimensions in the same report group can appear in the same report. Dimensions in different report groups cannot appear in the same report.

Events and report groups

Since you can create events and report groups independently, some report groups cannot exist for the lifetime of the event. For example, data that is acquired for the same dimension in two different report groups cannot be entirely consistent if the dimension was added to one of the report groups after the other one was added. As a result, you can end up trying to pivot on the dimension across report groups for a report period that does not exist in one of the report groups.

All events are automatically aggregated by the No Dimension Report Group report group, which cannot be disabled.

Events can be added to other report groups, as well.

Report Groups for Other Discover Products

Some Discover products can use report groups and dimensions.

Changes to Report Groups

Earlier, report groups did not exist specifically. However, the set of reference dimensions (Path, Server, Host, and Application) and their values essentially constituted a report group that was used to filter reports in the Portal.
