Media Analytics provides a number of standard dimensions that are based on data that the system inherently gathers from log data and Akamai's EdgeScape service.

Dimension information levels

Before you apply dimensions, you should understand how dimension levels are applied in Media Analytics.

Viewer level. These dimensions refer to a viewer's current session and all future sessions. Dimensions at the viewer level are also available with Visit and Play metrics, whereas metrics at the viewer level are available only with viewer level dimensions. You will have to restrict the number of distinct values per dimension to 5000000.
Visit level. These dimensions refer to viewer playback activity in a certain duration with one or more titles played during a visit. They can also be used with Play metrics.
Play level. These dimensions refer to a single title playback event. Attempts to play back video that resulted in errors are also included. These dimensions can only be used with Play level metrics.
