[Spike] Investigate accuracy of selection screen and monthly renders graphs for Electron
Closed, ResolvedPublic

Description

Background

In T175166: Cleanup and update Electron PDF Service grafana board, we created the updated graphs for Electron. In these, we noticed that the number of clicks to the selection screen was about half of the number of clicks for actually downloading a PDF. We'd like to double-check that this is correct.

Acceptance Criteria

Investigate how we pull data for the bottom four graphs https://grafana.wikimedia.org/dashboard/db/mediawiki-electronpdfservice?orgId=1 and document any possible inconsistencies

Event Timeline

Jdlrobson subscribed.

The data is pulled from calls to stat->increment inside Special:ElectronPdf (see https://phabricator.wikimedia.org/diffusion/EEPS/browse/master/src/specials/SpecialElectronPdf.php)

Any visit to Special:ElectronPdf will generate a electronpdf.action.show-download-screen (e.g. following this link)

The download of a pdf is only triggered when https://en.wikipedia.org/wiki/Special:ElectronPdf?action=redirect-to-electron&page=title is hit which happens when single column is selected and download is clicked.

I've added graphs for the 2 column layout.

I don't see any problem with the way the data is collected.

Looks good. We can conclude that approximately 50% of users do not continue to download.
