Prometheus===》普罗米修斯容器化监控、PromQL的使用、Grafana添加普罗米修斯数据源模板

一、普罗米修斯容器化

普罗米修斯容器化就是在kubernetes中安装。

#1.下载普罗米修斯配置清单
[root@gdx1 ~]# git clone -b release-0.5 --single-branch https://github.com/prometheus-operator/kube-prometheus.git
正克隆到 'kube-prometheus'...

remote: Counting objects: 100% (2/2), done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 8051 (delta 0), reused 1 (delta 0), pack-reused 8049
接收对象中: 100% (8051/8051), 4.54 MiB | 89.00 KiB/s, done.
处理 delta 中: 100% (4876/4876), done.
[root@gdx1 ~]# cd kube-prometheus/manifests/setup/
[root@gdx1 setup]# kubectl apply -f ./

#2.查看
[root@gdx1 setup]# kubectl get pods -n monitoring 
NAME                                   READY   STATUS    RESTARTS   AGE
prometheus-operator-848d669f6d-wpmdp   2/2     Running   0          85s

#3.部署普罗米修斯
[root@gdx1 setup]# cd ..
[root@gdx1 manifests]# pwd
/root/kube-prometheus/manifests
[root@gdx1 manifests]# kubectl apply -f ./

#4.做域名解析
[root@gdx1 manifests]# vim prometheus-ingress.yaml
