 Azure Private 5G Core can be configured to integrate with [Event Hubs](/azure/event-hubs), allowing you to monitor UE usage. Event Hubs is a modern big data streaming platform and event ingestion service that can seamlessly integrate with AP5GC. The service can process millions of events per second with low latency. The data sent to an Event Hubs instance can be transformed and stored by using any real-time analytics providers or batching or storage adapters.
 
 You can [monitor UE usage](/azure/event-hubs/monitor-event-hubs) based on the monitoring data generated by Azure Event Hubs, and analyze or alert on this data with [Azure Monitor](/azure/azure-monitor/overview).
 
+> [!IMPORTANT]
+> Azure Private 5G Core integration with Event Hubs is currently in [public preview](https://azure.microsoft.com/support/legal/preview-supplemental-terms/).

 ## Configure UE usage monitoring
 
 UE usage monitoring can be configured during site creation or at a later stage. If you want to configure UE usage monitoring for a site, please contact your support representative.
