after a 2xx response that rejects telemetry.

## \_ExportHealthTracker

### record\_unknown

```python theme={null}
def record_unknown(self) -> None
```

Clear acknowledgement health when the standard exporter reports another failure.

## DiagnosticOTLPSpanExporter

OTLP HTTP exporter that detects rejection acknowledgements returned with HTTP 2xx.

```python theme={null}
def get_export_health(owner: object) -> ExportHealth
```

Read acknowledgement health from an SDK exporter ownership surface.
