Our glossary for all of the Metrics and Dimensions that we currently support in the Watching That platform can be found here.
Everywhere Edition customers can augment this with Custom Metrics and Dimensions as they see fit. Those custom metrics won't be listed in this guide as they are unique to those specific customers using them.
Metrics & Dimensions have been marked with their availability based on the data source. (e.g. FreeWheel only, Collector API, etc)
