Hi Gergo -- I like this idea. As far as capacity, any EL-Hadoop based solution would be basically doing the same thing as you propose.
Can you please run it past ops (especially the 404 v 204) part?
Oliver -- the issue is that we'd like to figure out a way to provide accurate views of the media files; because of client side caching, we can't use the current requests. But your point is a good one -- we'll need to add this to the PV definition.

A nice theory, but if they appear in the webrequest table (presumably they would, and we're not creating an entirely new set of varnishes for the transmission of dummy images?) they have to be factored in. Again, however, the new definition automatically filters them by checking the webrequest source and MIME type, so this is not a problem, as I originally stated.

Oliver, this is not about pageviews, but about media file views.
These will be collected and dumped separately, as per

We would add a rule to Vagrant to make sure it does not try to look up
such
requests in Swift but returns a 404 immediately.
I bet ops would like it a lot better if this is a 204 and it kind of
makes
sense as it is the code used for beacons and such. Otherwise they might
get
alarms on 404s increasing.

Not really; the new pageviews definition wouldn't include those files anyway. It seems silly, thought, be deliberately generating a large amount of automated noise and client requests for this :/.

Hi all,
Erik Zachte is working on file view stats and is looking for a way to track Media Viewer image views (for which there is no 1:1 relation between server hits and actual image views); after some back and forth in https://phabricator.wikimedia.org/T86914 I proposed the following hack:
whenever the javascript code in MediaViewer determines that an image
view
happened (e.g. an image has been displayed for a certain amount of
time),
it makes a request to a certain fake image, say upload.wikimedia.org/wikipedia/commons/thumb/0/00/Virtual-imageview-
<real
image name>/<size>px-thumbnail.<ext> . These hits can than be easily filtered from the varnish request logs and added to the normal requests. We would add a rule to Vagrant to make sure it does not try to look up such requests in Swift but returns a 404 immediately.
This would be a temporary workaround until there is a proper way to log virtual image views, such as EventLogging with a non-SQL backend.
Do you see any fundamental problem with this?
