grafana+prometheus+metrics对kubernetes的监控配置⼀、监控选型
1. 选择⽤进⾏监控kubernetes。
2. ⽀持对k8s多集监控，操作简单。
3. ⽀持对应⽤的健康探测。
Requirements：
1. Currently only has support for
2. For automatic deployment of the exporters, then Kubernetes 1.6 or higher is required.
3. Grafana 5.0.0+
1)kube-state-metrics插件
2)node-exporter插件
3)prometheus插件
4)black-box-exporter插件
5)alertmanager插件
6)prometheus-webhook-dingtalk插件
