Analytics/Data Lake/Traffic/Virtualpageview hourly
The wmf.virtualpageview_hourly table (available on Hive) contains aggregated data about "virtual pageviews", i.e. user actions of consuming content on Wikimedia sites that are not proper pageviews, but are similarly focused on the content of a particular wiki page.
As of mid-2018, the only kind of virtual pageviews recorded in this table are page previews of Wikipedia articles on desktop (limited to previews popups that remain visible for at least one second). It contains valid data back to April 2018, and is viewable in Turnilo.
Internally, it is based on an auxiliary EventLogging table (Schema:VirtualPageView) where more detailed data is kept for 90 days, analogous to how wmf.pageview_hourly is generated as a "refinement" of the webrequest table. The format of this table also follows wmf.pageview_hourly as closely as possible (e.g. regarding information about the page being previewed, partitioning, information about the client like whether it is assumed to be a bot), in order to facilitate joins and other comparative analysis.
