After analysis, it should be caused by mqttclient acked the message，but the lack of ack mechanism in edge-to-cloud transmission.   

Thanks for following this project. At present, someone in the community has provided good technical solutions and simple code implementations. Can pay attention to other projects.

Updating device status has not been implemented before and is currently under development.https://github.com/kubeedge/kubeedge/pull/5649

看起来是因为你边端没有装cni-plugin,可以参考文档 https://kubeedge.io/zh/docs/faq/setup cni plugin not initialized的错误解决方案

Good job ! opentelemetry is a very popular monitoring framework currently. I think the method based on opentelemetry is very good. Others can also refer to this code to realize...
