Welcome to the Analytics Community!
Could you tell me more about the context of your query? What are you referring to as Action Metric?
I would also encourage you to introduce yourself to the community members - http://help-forums.adobe.com/content/adobeforums/en/analytics-forum/adobe-analytics.topic.html/forum...
I was hoping for an answer for this as well. My business user wants to know what an "Action"means in their Adobe dashboard. How is it calculated?
If Unique visits in June are 155,817 - and total actions is 1,703,608 what is actions/visit and actions/unique visitor?
How do I assess the total actions taken and then describe a ratio. For example x% of people went to Schedules, x% of people went to Training. Etc.
