Please measure with `at least a one-day granularity`
Access step:
[] how often the move-to link of the fileexporter was clicked - https://gerrit.wikimedia.org/r/#/c/413199/
[x] how often the fileimporter special page was visited
[] how often the page was inaccessible to users due to permissions - https://gerrit.wikimedia.org/r/413747
Preview step:
[] how often the import fails because of any exception, seperated by the reasons, e.g.
- a suppressed file (do we coun't each file once, of if there are multiple attempts, we count it multiple times?)
- missing info (e.g. first version of file could not be retrieved anymore)
- any of our max revisions limit is hit
- a failure of the abuse filter
Import Step:
[x] how many files were successfully moved
[x] how long it takes between users clicking the "import button" and redirecting to the commons page of a successful transfer
[x] the number of file revisions, number of text revisions, and total MB moved for files that were attempted to be moved
Misc:
[] add all new metrics variable to a metrics.md file in the docs folder of the respective extension
