You mean attach an X-analytics parameter, for extra images beyond the one the user initially requested.
But then we would undercount, basically missing all image views from clicking right arrow in image viewer. I'm not sure how much we would miss then. iirc Gilles said this browsing feature was used quite a long, but I'm not sure.

Subject: Re: [Analytics] Making EventLogging output to a log file instead of the DB Hi Gilles -- why won't the page view logs work by themselves for this purpose? EL can be configured to write into Hadoop which is probably the best way to get the throughput you need but it seems overcomplicated. -Toby On Tue, Jan 6, 2015 at 9:41 AM, Gilles Dubuc <gil...@wikimedia.org> wrote: This depends on [1] so we're not going to need that immediately, but in order to help Erik Zachte with his RfC [2] to track unique media views in Media Viewer, I'm going to need to use something almost exactly like EventLogging. The main difference being that it should skip writing to the database and write to a log file instead. That's because we'll be recording around 20-25M image views per day, which would needlessly overload EventLogging for little purpose since the data will be used for offline stats generation and doesn't need to be made available in a relational database. Of course if storage space and EventLogging capacity were no object, we could just use EL and keep the ever-growing table forever, but I have the impression that we want to be reasonable here and only write to a log, since that's what Erik needs. So here's the question: for a specific schema, can EventLogging work the way it does but only record hits to a log file (maybe it already does that before hitting the DB?) and not write to the DB? If not, how difficult would it be to make EL capable of doing that?
