一、IngressNginx监控

### --- IngressNginx监控

~~~     # IngressNginx监控官网地址：
~~~     https://kubernetes.github.io/ingress-nginx/user-guide/monitoring/

二、ingress nginx 监控配置：https://github.com/kubernetes/ingress-nginx/tree/master/deploy

三、实验环境配置

### --- 查看pod自动发现配置
~~~     查看daemonset自动发现配置

[root@k8s-master01 ~]# kubectl edit ds -n ingress-nginx ingress-nginx-controller
  annotations:
    prometheus.io/port: "10254"
    prometheus.io/scrape: "true"

### --- 查看pod自动发现配置
~~~     均开启了自动发现的annotations，端口为10254
~~~     告诉了Prometheus是可以被自动发现的

[root@k8s-master01 Ingressnginx监控]# kubectl get po -n ingress-nginx ingress-nginx-controller-7lpqc  -oyaml
  annotations:
    prometheus.io/port: "10254"
    prometheus.io/scrape: "true"

四、配置secrets

### --- 配置secrets

~~~     ——>http://krm.test.com/——>secrets——>Namespace:monitoring
~~~     ——>additional-scrape-configs——>编辑：最下面添加如下内容——>update——>END

- job_name: 'ingress-nginx-endpoints'
  kubernetes_sd_configs:
  - role: pod
    namespaces:
      names:
      - ingress-nginx
  relabel_configs:
  - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
    action: keep
    regex: true
  - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scheme]
    action: replace
    target_label: __scheme__
    regex: (https?)
  - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
    action: replace
    target_label: __metrics_path__
    regex: (.+)
  - source_labels: [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
    action: replace
    target_label: __address__
    regex: ([^:]+)(?::\d+)?;(\d+)
    replacement: $1:$2
  - source_labels: [__meta_kubernetes_service_name]
    regex: prometheus-server
    action: drop

五、配置dashboard

### --- 配置dashboard

~~~     # dashboard下载地址
~~~     https://github.com/kubernetes/ingress-nginx/tree/master/deploy/grafana/dashboards

### --- 导入dashboard
