 2. **Exporters:** Exporters are responsible for persisting the data. OpenTelemetry provides several out-of-the-box exporters, and OpenSearch supports the following:
     - `LoggingSpanExporter`: Exports spans to a log file, generating a separate file in the logs directory `_otel_traces.log`. Default is `telemetry.otel.tracer.span.exporter.class=io.opentelemetry.exporter.logging.LoggingSpanExporter`.
-    - `OtlpGrpcSpanExporter`: Exports spans through gRPC. To use this exporter, you need to install the `otel-collector` on the node. By default, it writes to the http://localhost:4317/ endpoint. To use this exporter, set the following static setting: `telemetry.otel.tracer.span.exporter.class=org.opensearch.telemetry.tracing.exporter.OtlpGrpcSpanExporterProvider`.
