k8s中prometheus監控k8s外mysql

k8s外安裝mysql

配置MySQL Exporter采集MySQL監控數據

創建yaml文件：vim mysql-exporter.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql-exporter
  namespace: monitoring
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: mysql-exporter
  template:
    metadata:
      labels:
        k8s-app: mysql-exporter
    spec:
      containers:
      - name: mysql-exporter
        image: registry.cn-chengdu.aliyuncs.com/qzcsbj/mysqld-exporter:v0.12.1
        env:
         - name: DATA_SOURCE_NAME
           value: "root:123456@(192.168.117.160:3306)/"
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 9104
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-exporter
  namespace: monitoring
  labels:
    k8s-app: mysql-exporter
spec:
  type: ClusterIP
  selector:
    k8s-app: mysql-exporter
  ports:
  - name: mysql-exporter-api
    port: 9104
    protocol: TCP

 

創建exporter：kubectl create -f mysql-exporter.yaml

查看資源：kubectl get -f mysql-exporter.yaml

 

查看pod：kubectl get po -n monitoring |grep mysql-exporter

 

查看svc：kubectl get svc -n monitoring |grep mysql-exporter

 

查看是否獲取到監控數據：curl 10.109.182.129:9104/metrics | grep max_connections

 

創建sm

 

 

prometheus中查看數據

查看prometheus的svc：kubectl get svc -n monitoring | grep prometheus

 

請求：http://192.168.117.161:30576

target中，prometheus自動發現了mysql

 

config中，自動生成了配置文件

 

查詢數據：max_connections（要手動輸入，不能復制粘貼）

mysql_global_variables_max_connections

 

grafana中查看數據

查看grafana的svc：kubectl get svc -n monitoring | grep grafana

 

請求：http://192.168.117.161:31239/

導入模板：https://grafana.com/grafana/dashboards/7362

 

然后選擇數據源

 

效果
