1 集群资源监控概述
1）监控指标
集群监控：①节点资源利用率；②节点数；③运行Pods；
Pod监控：①容器指标；②应用程序指标；
2）监控平台搭建方案 Prometheus + Grafana
Prometheus：①开源；②监控，报警，数据库；③以http协议周期性抓取被监控组件状态；④集成简单，使用http接入即可；
Grafana ：①开源的数据分析和可视化工具；②支持多种数据源；
2 监控平台搭建
2.1 平台搭建准备
安装资源链接: kubernetes性能监控平台prometheus和grafana
mkdir /opt/module/pgmonitor
将资源解压到/opt/module/pgmonitor
查看解压后的目录文件结构
tree /opt/module/pgmonitor
=============================
/opt/module/pgmonitor

│ ├── grafana-deploy.yaml
│ ├── grafana-ing.yaml
│ └── grafana-svc.yaml
├── node-exporter.yaml
└── prometheus
├── configmap.yaml
├── prometheus.deploy.yml
├── prometheus.svc.yml
└── rbac-setup.yaml
2 directories, 8 files
2.2 部署守护进程
kubectl delete -f node-exporter.yaml
==============================
daemonset.apps "node-exporter" deleted
service "node-exporter" deleted
kubectl create -f node-exporter.yaml
==============================
daemonset.apps/node-exporter created
service/node-exporter created
2.3 部署prometheus
kubectl create -f rbac-setup.yaml
==============================
clusterrole.rbac.authorization.k8s.io/prometheus created
serviceaccount/prometheus created
clusterrolebinding.rbac.authorization.k8s.io/prometheus created
kubectl create -f configmap.yaml
==============================
configmap/prometheus-config created
kubectl create -f prometheus.deploy.yml
==============================

2.4 部署grafana
kubectl create -f grafana-deploy.yaml
==============================
deployment.apps/grafana-core created
kubectl create -f grafana-svc.yaml
==============================
service/grafana created
kubectl create -f grafana-ing.yaml
==============================
