We might get the pageview data for free. I know that http://tools.wmflabs.org/pageviews/ supports page views for special pages, but I'm not sure how it deals with subpages (like Special:CreatePage/Puppies). Maybe @MusikAnimal would know. Do subpage page views roll-up into the parent page stats? I bet they don't. Is there any way to view the page views for a page and all it's subpages?

As far as I know any page that goes through Varnish should be recorded, including Special pages. Subpages definitely don't bubble up to the parent, that much I'm sure. See example of Special:Log vs Special:Log/block: http://tools.wmflabs.org/pageviews/?project=en.wikipedia.org&platform=all-access&agent=user&range=latest-20&pages=Special:Log|Special:Log/block

Massviews does this, but going by the MediaWiki API it doesn't know about "subpages" of Special pages (if you really want to call them subpages). I'm not sure how to automate detection of these pages. If we can figure that out I can fix Massviews to support it.

Hmm, this might be a lot harder than I thought. The pageview stats are going to be different for every page title, so there's no easy way to roll it up without doing some expensive queries on the raw pageview data. Also, it doesn't look like there's any way to execute JavaScript from the clickable button template. We would have to add some JS to common.js which would bloat page load for everyone. I'm wondering if we should re-think making the entire page live on-wiki, as this makes analytics difficult.

After talking with @MaxSem, we've decided to append the requested page title as a query string parameter rather than as a subpage so that we get pageview data for free via the pageview API.
