Pod 和容器，典型的比如创建 Pod、销 毁 Pod，显然我们应该关注这些操作的 成功率和耗时 • Categraf 的仓库中 inputs/kubernetes/kubelet-metrics- dash.json 就是 Kubelet 的大盘文件 • kubelet_running_pods：运行的Pod的数量，gauge类型 • kubelet_running_containers：运行的容器的数量，gauge类型， 修改 iptables 或者 ipvs。所以要重点关 注 sync_proxy_rules 相关的指标 • Categraf 的仓库中 inputs/kubernetes/kube-proxy- dash.json 就是 kube-proxy 的大盘文件 • up 关注 kube-proxy 的存活性，应该和 node 节点的数量相等 • rest_client_request_duration_seconds 也会缓存很多数据到内存里，所以进程占用的 内存，所在机器的内存使用率都应该要关注 • 采集方式可以参考 categraf 仓库的 k8s/deployment.yaml，大盘可以参考 k8s/apiserver- dash.json • apiserver_request_total 请求量的指标，可以统计每秒请求数、成功率 • apiserver_request_duration_seconds 请求延迟统计 •

line width, before beveling the join instead. • dashPhase Starting offset for dash pattern. • dashes Array of on/off dash lengths. {dashes:[5,10], lineWidth:3, lineCap:'Round'} 6.4. Object Protocols the number of items in the border dash pattern. Returns Integer. var dashCount = annotation.getBorderDashCount(); getBorderDashItem(i) Returns the length of dash pattern item i. Arguments • i – the annotation border dash pattern to the given array of dash item lengths. The supplied array represents the respective line stroke and gap lengths, e.g. [1,1] sets a small dash and small gap, [2,1,4
