**Need:** To improve 2ColConf we would like to know how it is used and how it does compared to the current conflict resolvent page
GENERAL:
* All following metrics should be collected together for each conflict and matchable to each other. Events should be in the order they happened in. So the format ideally would be:
* If applicable, metrics should be collected for the old UI as well as for the 2ColConf
* **Infos on the conflict** (for old and new version)
** **Namespace** of page the conflict happened on (Q: //"How does behavior on talkpages differ from articles?"//) | should be a STRING
** Amount of **conflicting text** (as characters or words) (Q: //"How does behavior differ between huge or small conflicts?"//) | should be a INTEGER
* **User behavior**: (only partly applicable)
** Text **input actions** to the Editor (could be just the amount of keypresses or +- editied) (Q: //"Did people actually use the possibility to do edits in the editor?"//) | should be an INTEGER
** **Filters used** (Q: //"Do people use the filter options? Do they always switch to a particular one (which could be default then)"//). Should be an ARRAY with STRING or possibly an ARRAY with OBJECTS with STRING and relative timestamp as INTEGER
* **Leaving the page** : Do they… (for old and new version) | should be a STRING
** Use the save button (Which would indicate the feature helped them)
** Do they use the Cancel button
** Do they navigate away via the browser (Back, Tab Close etc.)
== Outcome
We've implemented this feature, and here is an accounting of the data we record:
* EventLogging: [[ https://meta.wikimedia.org/wiki/Schema:EditConflict | EditConflict schema ]].
** User ID, and name or IP address
** Calculated user attributes: is anonymous, edit count
** Page ID, namespace, and title
** Revision ID of the page's latest, conflicting "other" revision
* EventLogging: [[ https://meta.wikimedia.org/wiki/Schema:TwoColConflictConflict | TwoColConflictConflict schema ]]
** Was this the legacy or TwoColConflict workflow?
** Page namespace
** Revision IDs for the previous edit and conflicting "other" edit
** Literal wikitext "your" edit as entered into the edit text box
* Statsd MediaWiki-core "edit.failures.conflict"
** Count of edit failures due to a conflict. Segmented by namespace (some namespaces are omitted) or user edit count bucket (but the two cannot be joined).
** Resolved conflict count, segmented by namespace or user edit count bucket
* Statsd [[ https://phabricator.wikimedia.org/diffusion/ESCC/browse/master/docs/metrics.md | MediaWiki.TwoColConflict ]]
** Pageload count (can this be more than the number of conflicts?). Segmented by namespace, and by user edit count bucket (but the two cannot be joined).
** Conflicts resolved, segmented by namespace or user edit count bucket
