Feature Flags

Feature flags and advanced settings

To set up a flagged feature or other advanced setting, add the name of the feature key (observability:myFeature) to common/ui_settings_keys.ts and the feature parameters to server/ui_settings.ts.

Test for the feature like:

import { myFeatureEnabled } from '../ui_settings_keys';
if (core.uiSettings.get(myFeatureEnabled)) {
  doStuff();
}

In order for telemetry to be collected, the keys and types need to be added in src/platform/plugins/private/kibana_usage_collection/server/collectors/management/schema.ts and src/platform/plugins/private/kibana_usage_collection/server/collectors/management/types.ts.

Settings can be managed in Kibana under Stack Management > Advanced Settings > Observability.
