General questions
1

I want to track each user and the pages he visits I am sending user id in Piwik like this
_paq.push(['setCustomVariable', 1, "user_id", "<%= current_user.id %>", "page" ]);

In Piwik app I can see this custom variable but I cant see which user visits which pages
(like user with id 111 viewed dashorad for 2 mins, all users page for 2 mins and so on… )

I am working on rails app
