9.kube-state-metrics组件介绍
kubernetes-state-metrics:通过监听API Server生成有关资源对象的状态指标,比如Deployment、Node、Pod,需要注意的是kube-state-metrics只是简单的提供一个metrics数据,并不会存储这些指标数据,所以我们可以使用Prometheus来抓取这些数据然后存储,主要关注的是业务相关的一些元数据,比如Deploument、Pod、副本状态等,调度了多少个replicas?现在可用有几个?;多少个Pod是running/stopped/terminated状态?;Pod重启了多少次?;我有多少job在运行中。
kube-state-metrics (KSM) is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.
