Due to lack of exact eventlogging on the usage of the relief data or mapnik layer used in Wikivoyage (and elsewhere), let's get some set up.
See this link for a map on Wikivoyage and click on the layer icon on the top right to see it in action: https://en.wikivoyage.org/wiki/Wikivoyage:Travellers%27_pub#.22API_Key_Required.22

| Resolved | mpopov | T171020 Maps: figure out usage of layer data in Wikivoyage maps |
Found where layer selection events are implemented: https://github.com/wikimedia/mediawiki-extensions-Kartographer/blob/master/modules/wikivoyage/WVMapLayers.js
Shouldn't be too hard to add layer name into the extra field.

I am not familiar enough with the event object in the context of Maps and had to make a lot of assumptions based on the surrounding code, so I'm not 100% sure that I'm correct in trying to get the name of the layer via event.layer in https://gerrit.wikimedia.org/r/#/c/366183/2/modules/wikivoyage/WVMapLayers.js. I'm hoping @MaxSem can confirm that I did it correctly or provide some advice for how to do it properly.

It worked! We're now tracking external layer names. Doesn't look like they are widely used, though:
SELECT wiki, event_action AS action, REPLACE(SUBSTR(REGEXP_SUBSTR(event_extra, '"layer":"(.*)"'), 9, 100), '"', '') AS layer, COUNT(DISTINCT(event_userToken)) AS sessions, COUNT(*) AS events FROM Kartographer_16132745 WHERE LEFT(timestamp, 8) >= '20170817' AND event_action RLIKE 'exlayer$' AND event_extra RLIKE '"layer"' GROUP BY wiki, action, layer;
| wiki | action | layer | sessions | events |
|---|---|---|---|---|

Cool! Was the data noted above for only one day ( 20170817)?
We'll need to look at adding this new data point into the maps dashboard and/or in grafana.
No, from 4 Aug to 21 Aug. On a daily basis it's like 1-2 counts per layer.

Yeah, once things are resolved with the metric calculations I'd like to add this and other metrics to the Maps dashboard.
