A: In eZanalytics, there is an option to tag a set of pages that you would like to monitor closely using Add pages to list(see below screenshot from chrome plugin), and then you can go to the Crewmachine to see the overall performance of these tagged pages.
Also, If you just want to see the performance of pages one by one, then you need to open that page in the browser and then you can see the performance of that page in eZanalytics plugin(with graphical representation) for the last 30 days at the bottom under “Page Performance” section.
