Hi @eamedina
Here is an example of the logs when viewing a story:

event: {

  "$schema": "/analytics/mediawiki/wikistories_consumption_event/1.0.0",
  "meta": {
    "stream": "analytics/mediawiki/wikistories_consumption_event",
    "domain": "localhost",
    "dt": "2022-05-13T22:58:47.599Z",
    "id": "f1db9ce3-0744-4b56-8fc1-3fd5ed8a8562",
    "request_id": "3fe0b030-d310-11ec-8833-0b77b8c8e58c"
  "activity_session_id": "85ea4027dcf22786c1d1",
  "pageview_id": "2ef12c30e7385ea276d8",
  "access_method": "mobile web",
  "page_title": "Coconuts",
  "event_type": "story_view",
  "story_title": "Whites",
  "story_frame_count": 3,
  "story_frames_viewed": 3,
  "story_completed": true,
  "story_open_time": 15007,
  "page_story_count": 2,
  "dt": "2022-05-13T22:58:47.599Z"

Comparing with the example given in the ticket description, I notice some fields relating to session and experiment are not present. Is this a problem?

@EUdoh-WMF that's fine, those fields missing are expected. The missing fields will be included later after initial release, according to the Wikistories evaluation plan. Thanks for checking!
