@sqren Is this also tracking data streams support within the UX app to enable users to view their data if they update their apm server integration?

@formgeist In #89650 I added the fleet indices to the indicies we normally query. So as long as the UX team is using apmEventClient.search they should be fine (like here):

kibana/x-pack/plugins/apm/server/lib/rum_client/get_web_core_vitals.ts

Line 106 in 5a9fc21

const response = await apmEventClient.search(params);

@sqren Great, seems like it's covered already 👍
