Prometheus ServiceMonitor

 

創建一個新的serviceMonitor就創建了一個prometheus的target

[root@k8s-m1 ~]# cat ServiceMonitor.yaml apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata:  labels: k8s-app: xxx-exporter  name: xxx  namespace: prometheus spec:  endpoints: - interval: 15s  port: xxx-exporter  jobLabel: xxx-exporter-monitor  namespaceSelector:  matchNames: - monitor #目標服務的namespaces  selector:  matchLabels: k8s-app: xx-exporter 目標服務的labels 

  namespaceSelector:
    any: true 選擇所有的namespace

上面ServiceMonitor是針對k8s集群內部服務監控，想監控集群外部的exporter通Endpoints實現

# 為外部 exporter 服務設置 service kind: Service apiVersion: v1 metadata:  namespace: monitor  name: service-mysql-xx  labels:  app: service-mysql-xx spec:  ports: - protocol: TCP  port: 9xx  targetPort: 9xx  type: ClusterIP  clusterIP: None --- kind: Endpoints apiVersion: v1 metadata:  namespace: monitor  name: service-mysql-xx  labels:  app: service-mysql-xx subsets: - addresses: - ip: x.x.x.x  ports: - protocol: TCP  port: 9xxx

ServiceMonitor

apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata:  name: service-mysql-xx  labels:  app: service-mysql-xx spec:  selector:  matchLabels:  app: service-mysql-xx  namespaceSelector:  matchNames: - monitor  endpoints: - port: metrics  interval: 10s  honorLabels: true
