All Implemented Interfaces:
```
public class OtlpMetricsClient

                    
```
OTLP gRPC client for sending metrics to line-est receiver. Uses OpenTelemetry protobuf format for metric export. This client is Java 8 compatible and connects to line-est's OtlpMetricsReceiver on the configured endpoint (default: localhost:4317).
