Viewing a data stream

BMC Helix Edge ships a predefined data stream called enrichedStream. This stream acquires contextual data from connected devices, sensors, and external systems and helps configure the rules. 

The data source signifies where the data originates, and the stream type specifies its classification, such as EdgeX. The configuration keys are used for enrichment data, providing additional information to enhance the data. Stream formats in JSON define the structure in which the data is presented. They represent real-time or historical data. You can use this data in Rule Designer to create rules based on specific conditions or events.

Before you begin

• Make sure that devices, sensors, or systems generating data streams are connected and integrated with BMC Helix Edge.
• Confirm that active data streams are available in the BMC Helix Edge environment. Data streams are sourced from devices or external systems.
• Verify that the configuration for data sources is correctly set up. Configuration details might include authentication, endpoint settings, and other parameters depending on the data source.

To view a data steam

Use the following steps to view and understand the details of Rule Designer's data streams to create rules customized to specific use cases.

1. On the BMC Helix Edge page, select Rules and workflows > Rule Editor.
2. On the left pane of the Rule Designer page, select a node to view a stream.
3. In the Configure Nodes pane, click the Streams tab.
4. In the Streams tab, click a steam.
   BMC Helix Edge displays the following panel:
   

5. In the View Stream panel, observe the following fields:

   Field	Description
   Name	Indicates the identifier for the data stream.
   Datasource	Specifies the origin or provider of the data. In this case, the data source is enrichedStream.
   Stream type	Specifies the type of stream, such as EdgeX.
   Configuration Key	Refers to the configuration key associated with enrichment data.
   Stream format	Indicates the format of the stream in JSON.
