Calculated metrics

Calculated metrics for Adobe streaming media services are custom metrics built from the standard streaming media metrics, letting you derive ratios such as average ad time spent or media completion rate without changing your implementation.

To create these calculated metrics in Analysis Workspace, see the respective calculated metrics overview in Adobe Analytics or Customer Journey Analytics.
