红帽全球峰会2.3. 查看节点
您可以显示节点的用量统计，这些统计信息为容器提供了运行时环境。这些用量统计包括 CPU、内存和存储的消耗。
查看用量统计：
oc adm top nodes
$ oc adm top nodes输出示例
查看具有标签的节点的用量统计信息：
oc adm top node --selector=''
$ oc adm top node --selector=''
您必须选择过滤所基于的选择器（标签查询）。支持 =、== 和 !=。
注意
您必须有 cluster-reader 权限才能查看用量统计。
注意
必须安装 metrics-server 才能查看用量统计。请参阅使用 Horizontal Pod Autoscalers 的要求。
