The DeepFlow Agent needs to inject VPC and IP tags into the data so that the DeepFlow Server can extend all other tags based on them. For tracing data, we want the OpenTelemetry Agent to label IP information for the DeepFlow Agent. Fortunately, the k8s attributes processor (opens new window) plugin can automatically inject the IP address of the Span sender, and attribute.net.peer.ip can be automatically injected by most OpenTelemetry Instrumentations.

With DeepFlow’s AutoTagging capability, we can automatically associate tracing data with other observability data, without requiring developers to insert any code.
