Please measure with `at least a one-day granularity`
[] how often the move-to link of the fileexporter was clicked
[] how often the fileimporter special page was visited
[] how many files were successfully moved
[] how long it takes between users clicking the "import button" and redirecting to the commons page of a successful transfer
[] 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
[] the number of file revisions, number of text revisions, and total MB moved for files that were attempted to be moved
[] If something is not explained in the schema file (whose link should appear in this ticket), add all new metrics variable to a metrics.md file in the docs folder of the respective extension
