+- `logsApiLevel`: Minimum log severity to export (defaults to `INFO`). Set to `ObservabilityOptions.LogLevel.NONE` to disable log exporting.
+- `tracesApi`: Controls trace recording (defaults to enabled). Use `ObservabilityOptions.TracesApi.disabled()` to disable all tracing, or set `includeErrors`/`includeSpans`.
+- `metricsApi`: Controls metric export (defaults to enabled). Use `ObservabilityOptions.MetricsApi.disabled()` to disable metrics.

 ### Recording Observability Data
 
 After initialization of the LaunchDarkly Android Client SDK, use `LDObserve` to record metrics, logs, errors, and traces:
