kubernetes（k8s）装置 Prometheus + Grafana
组件阐明
MetricServer：是 kubernetes 集群资源应用状况的聚合器，收集数据给 kubernetes 集群内应用，如 kubectl,hpa,scheduler 等。
PrometheusOperator：是一个零碎监测和警报工具箱，用来存储监控数据。
NodeExporter：用于各 node 的要害度量指标状态数据。
KubeStateMetrics：收集 kubernetes 集群内资源对象数 据，制订告警规定。
Prometheus：采纳 pull 形式收集 apiserver，scheduler，controller-manager，kubelet 组件数 据，通过 http 协定传输。
Grafana：是可视化数据统计和监控平台。
