Where can I see the stats for Google Analytics +?

I've installed the plugin on a multisite install and logged in to my google account in the network admin panel.
I have a few questions:
1) How can I see the analytics panel? I have no menu item except the settings.
2) How do I add the panel to the dashboard?
3) Would each blog admin see stats related to his own blog when using this plugin? Are stats taken using the codes I've entered in the network admin panel or does he need to configure it by himself?
4) Do I need to add the tracking codes if I logged in to my google account?
