Forwarding Data to DIS

Scenarios

Forwarding data to Data Ingestion Service (DIS) allows you to collect, process, and distribute real-time streaming data efficiently. DIS interconnects with multiple third-party data collection tools and provides cloud service connectors, agents, and SDKs. You can also dump data to other cloud services for subsequent data processing like data storage and analysis.

Purchasing a DIS Stream (Example: Forwarding Data to DIS and Dumping Data to OBS)

1. Log in to the Object Storage Service (OBS) console.
2. Click Create Bucket, configure the parameters as required, and click Create Now.
3. In the bucket list, click the created bucket. The Objects page is displayed. Click Create Folder and enter a folder name as prompted.
4. Access the Data Ingestion Service (DIS) service page.
5. Click Access Console to go to the DIS console.
6. Click Buy Stream in the upper right corner, configure parameters as required, and click Next.

7. In the navigation pane, choose Stream Management and click a purchased stream. Click the Dump Tasks tab. Click Create Dump Task. Set Dump Destination to OBS, Dump Bucket to the bucket created in 2, and File Directory to the folder created in 3. Click Create Now.

Configuring IoTDA

You can configure data forwarding rules in IoTDA to forward data reported by devices to DIS.

1. Access IoT Device Access and click Access Console. Click the target instance card.
2. In the navigation pane, choose Rules > Data Forwarding, and click Create Rule in the upper left corner.
3. Set the parameters based on the table below. The following parameter values are only examples. You can create your own rules by referring to Procedure. After setting the parameters, click Create Rule.

   Table 1 Rule parameters

   Parameter	Description
   Rule Name	Description: Customize a name, for example, iotda-dis.
   Description	Description: Customize a description, for example, forwarding data to DIS.
   Data Source	Description: Select Device property.
   Trigger	Description: Device property reported is automatically configured.
   Resource Space	Description: Select All resource spaces.

4. Click the Set Forwarding Target tab, click Add to set a forwarding target, and click OK.

   Table 2 Forwarding target parameters

   Parameter	Description
   Forwarding Target	Description: Select Data Ingestion Service (DIS).
   Region	Description: Currently, you can only forward data to DIS in the same region. If IoTDA is not authorized to access the service in this region, configure cloud service access authorization as prompted.
   Stream Homing	Description: Select either In-house stream or Delegated by others.
   Stream	Description: Select a stream.

5. Click Enable Rule to activate the configured data forwarding rule.

Verifying Configurations

• You can use a registered physical device to access the platform and enable the device to report data.
• You can also use a simulator to simulate a device to report data. For details, see Developing an MQTT-based Simulated Smart Street Light Online.

Expected result:

Log in to the OBS console, click the bucket created in 2, and click the folder created in 3 to view the latest data forwarded from DIS to OBS.
