The cloud-edge-device collaborative architecture has emerged as a pivotal computing paradigm, integrating centralized cloud resources with distributed edge capabilities to optimize data processing and task execution. By synergizing the strengths of both domains, this architecture addresses the concurrent requirements for low latency, high throughput, and energy efficiency. However, the inherent complexity of such systems—characterized by heterogeneous terminal devices, diverse network topologies, and stringent performance constraints—presents significant challenges for system management and troubleshooting. Effective fault detection, diagnostics, and performance optimization necessitate a robust monitoring framework supported by granular data metrics. This Recommendation defines a comprehensive set of monitoring parameters for the cloud-edge-device collaboration systems. By establishing a standardized monitoring framework, this document serves as a technical reference for the implementation of monitoring capabilities, facilitating the design, deployment, and lifecycle maintenance of resilient collaborative environments.
