首先部署prometheus
首先是pvc
apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: prometheus-data-pvcnamespace: monitor
spec:accessModes:- ReadWriteManystorageClassName: "data-nfs-storage"resources:requests:storage: 10Gi
然后接着 cluster-role 这里给了cluster-admin权限
apiVersion: v1
kind: ServiceAccount
metadata:name: prometheus2namespace: monitor
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:name: prometheus2
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:

由于用的是istio 所以这里的ingress用vs替代
apiVersion: v1

--- 这些yaml文件其实已经做好了一些基本组件的监控 但是如果要监控外部比如mysql
举个例子吧
监控mysql
我们用独立部署exporter方式来做监控 避免对k8s侵入过多
# 下载
curl http://stu.jxit.net.cn:88/k8s/mysqld_exporter-0.14.0.linux-amd64.tar.gz -o a.tar.gz
# 解压
tar -xvf a.tar.gz
创建mysql监控账号
CREATE USER 'exporter'@'<安装Prometheus的主机IP>' IDENTIFIED BY '<your password>';
GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'<安装Prometheus的主机IP>';
flush privileges;
my.cnf
cat <<E0F>> my.cnf
[client]
host = xxxx
port = xxxx
user = xxxxx
password= xxxx
启动mysql exporter
nohup ./mysqld_exporter --config.my-cnf=my.cnf &
最后在grafana的web界面中 点击import 输入 15757 15759 对应的k8s基本信息监控 和节点基本信息监控
效果如下
最后想说一句话
不要局限于组件本身 比如这一套组件
要目标导向的去找组件 比如我想监控什么metric
