Exporter（Elasticsearch监控）

一、部署 elasticsearch_exporter

  不多bb，直接上配置清单 yaml文件：

kind: Pod
apiVersion: v1

二、与 Prometheus 集成

  与 Prometheus 的配置文件 prometheus.yaml 中的 static_configs 模块内，继续追加配置内容来采集 elasticsearch_exporter 提供的数据。添加的参考配置内容如下： 

scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]
	
  - job_name: "elasticsearch_exporter"
    static_configs:
	  - targets: ["192.168.2.121:9108"]
