Screen.Recording.2023-09-25.at.17.10.33.mov

Notes

1. ~~Storing the dashboard name in the saved object may become outdated and cause confusion, as users have the ability to update the dashboard title on the dashboard page.
   [UPDATED] Fetch dynamically from the dashboard module api
2. UI we don't have an indicator useContextFilter
3. This fixes a bug related to service.environment. Please see the changes to x-pack/plugins/apm/public/components/app/metrics/static_dashboard/index.tsx

nit: is there such a thing as a "linked custom dashboard"? Or is it merely a linked dashboard? Or a custom dashboard? Or just a dashboard?

[kpatticha]

hm, since I did the renaming I believe this needs to change to getCustomDashboards to avoid confusion. WDYT?

Saved Objects .kibana field count

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/saved-objects-service.html#_mappings
