+## Feature Gates
+
+This component has the following feature gates:
+
+| Feature Gate | Stage | Description | From Version | To Version | Reference |
+| ------------ | ----- | ----------- | ------------ | ---------- | --------- |
+| `metricsgeneration.MatchAttributes` | alpha | When enabled, the metric calculations will only be done between data points whose attributes match. | v0.112.0 | N/A | [Link](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/35425) |
+
+For more information about feature gates, see the [Feature Gates](https://github.com/open-telemetry/opentelemetry-collector/blob/main/featuregate/README.md) documentation.
