操作系统信息

集群使用kk命令部署。node1和node2是x86 Ubuntu22，node3是arm Kylin v10。

问题是什么
x86节点上的监控信息可以正确显示，arm节点上的监控信息不显示:

另外使用以下脚本避免一些ds再边缘节点运行

#!/bin/bash

NoShedulePatchJson='{"spec":{"template":{"spec":{"affinity":{"nodeAffinity":{"requiredDuringSchedulingIgnoredDuringExecution":{"nodeSelectorTerms":[{"matchExpressions":[{"key":"node-role.kubernetes.io/edge","operator":"DoesNotExist"}]}]}}}}}}}'
ns="kube-system"
DaemonSets=("nodelocaldns" "kube-proxy" "calico-node")
length=${#DaemonSets[@]}
for((i=0;i<length;i++));  
do
    ds=${DaemonSets[$i]}
    echo "Patching resources:DaemonSet/${ds}" in ns:"$ns",
    kubectl -n $ns patch DaemonSet/${ds} --type merge --patch "$NoShedulePatchJson"
    sleep 1
done

补充：边缘节点上有监控信息

看pod列表，感觉扩展组件安装是不是不太齐全，麻烦贴一下您这个环境中安装了哪些扩展组件以及组件配置吧
