Configure Azure IoT Central continuous data export to stream device data to Blob Storage, Event Hubs, or Service Bus

Steps

1. Confirm you have the Data export permission in your IoT Central application
2. Create the destination resource (Storage account/container, Event Hubs namespace/hub, or Service Bus namespace/queue or topic) and assign your IoT Central app's system-assigned managed identity the matching role (Storage Blob Data Contributor for Blob Storage, Azure Event Hubs Data Sender for Event Hubs, Azure Service Bus Data Sender for Service Bus)
3. In IoT Central, go to Data export > + New destination, pick the destination type, choose managed identity or connection string auth, and enter the endpoint/host name plus container, event hub, or queue/topic name
4. Create a new export: select the data type(s) to stream (telemetry, property changes, device connectivity, device lifecycle, device template lifecycle, or audit logs), optionally add filters and enrichments
5. Attach the destination(s) to the export (up to 5 per export) and save — data begins streaming continuously from that point forward in near real time (Blob Storage batches and writes once per minute)
