Change Details

== Background In {T180036}, we added an additional piece of data to every event sent by the EventLogging instrumentation that would allow us to identify the typical time to first link interaction on a page, accurate to less than 1 ms. We did this because the timestamps available to us from the server-side were only accurate to the second (see T179426#3741809 onwards). In {T178500}, the EventLogging instrumentation was disabled. Obviously, we need to enable it. == Developer Notes # This is as simple as setting `$wgPopupsEventLogging = true` in [[ https://github.com/wikimedia/operations-mediawiki-config | the config ]] for English and German Wikipedia only. # The logging should be disabled eight days after enabling it. (We want to collect a full week's worth of data, allowing, as last time, an additional day for the initial change to propagate.) == Post-deploy Actions [] Notify Analytics Engineering of the date and time that the instrumentation was enabled so that they can drop data that they've already collected with broken timestamps (see {T182000} for more detail).

NOTE: Blocked until after the train rolls out of the station on Thursday, 7th December as the fix for T182000 will be riding the train. == Background In {T180036}, we added an additional piece of data to every event sent by the EventLogging instrumentation that would allow us to identify the typical time to first link interaction on a page, accurate to less than 1 ms.
