Metadata

If the metadata Level is set to Low, Medium, or High in the Diagnostics and metadata, adapter streams created by the ingress components include the following metadata:

Datasource: {ComponentId} AdapterType: {ComponentType}

ComponentId corresponds to the adapter components' data source configured in the Configure system components. ComponentType corresponds to the adapter type.

Metadata for health and diagnostics streams

If you configure a health endpoint and enable metadata, they are included in the health streams (Device status and Next health message expected) together with ComponentId and ComponentType.

If you enable diagnostics in Diagnostics and metadata, metadata are included in the diagnostics streams (Stream count, Adapter IO rate, Error rate) together with ComponentId and ComponentType.

The adapter may also send its own stream metadata not including health and diagnostics streams. For more information about what custom metadata is included in each stream, see the user guide for your adapter.

Note: Metadata is only sent for streams created by the ingress components. Currently, the only endpoint that persists sent metadata is CONNECT data services.
