I run multiple domains that are not related to each other and are all tracked by Google Analytics on separate web properties (different tracking code, same Google Account).
I am wondering if there is a way by which I could view all of the stats combined (e.g. total pageviews, visitors, or even total real-time users browsing all of my sites right now). I don't mind connecting my Google Analytics account with 3rd party apps which would analyse the data.
With the real-time viewer stats I could then perhaps estimate the capacity of my web server. Otherwise, simply knowing how many people visited your site this month, without having to manually add all stats together, is something that is nice to know and allows you to see your overall performance of your sites.
