Why Huawei Cloud network monitoring misses the hardest faults

The article argues that Huawei Cloud's native monitoring tools fail to detect complex network faults because they lack the ability to correlate data across different layers, such as linking VPC traffic patterns directly to application latency. While CloudEye and VPC Flow Logs provide valuable individual metrics, a critical gap remains in automatically mapping these events to broader network topology and resource pressure. To solve this, the author advocates for an advanced observability layer that integrates disparate data sources into a unified, proactive system for real-time troubleshooting.
