1. Is this request related to a challenge you're experiencing? Tell me about your story.

We have integrated the OpenTelemetry SDK with automatic instrumentation for infrastructure components (HTTP, DB, Redis, Celery). But the collected telemetry data is very limited—only infrastructure-level spans are captured.

The existing OpsTrace mechanism captures Workflow execution data; however, its asynchronous post-execution collection model differs from OpenTelemetry's real-time instrumentation, making direct trace correlation impossible.

We suggest adding OpenTelemetry instrumentation to the business layer. The proposed instrumentation targets include: AppGenerateService.generate() (entry point), various AppRunner.run() methods (e.g., WorkflowAppRunner, ChatAppRunner), Workflow and Node execution, LLM model invocations, and RAG retrieval calls.
