[root@localhost ~] cd /usr/local/prometheus/
[root@localhost prometheus] mkdir targets
[root@localhost prometheus] vi targets/dev_node.json 

[
  {
    "targets": [ "192.168.1.5:9090","127.0.0.1:9090" ],
    "labels": {
      "env": "dev_webgame"
    }
  }
]

集成prometheus

[root@localhost prometheus] vi prometheus.yml

  - job_name: 'node_service_discovery'
    file_sd_configs:
    - files: 
      - targets/*.json
      refresh_interval: 60m

[root@localhost prometheus] systemctl restart prometheus

由于配置的两个地址不存在，所以显示DOWN

配置文件说明：
file_sd_configs，指定prometheus基于文件的服务发现配置使用的选项

• files，自定义的和prometheus程序同级目录的targets目录，要被自动加载的所有.json格式的文件。当然也可以单独指定某一个JSON格式的文件。
  refresh_interval: 60m，自定义刷新间隔时间为60秒

[root@localhost prometheus] vi targets/dev_node.yaml 

- targets:
  - "192.168.1.30:9100"

[root@localhost prometheus] vi prometheus.yml

  - job_name: 'node_service_discovery'
    file_sd_configs:
    - files:
      - targets/*.json
      refresh_interval: 60m
    - files:
      - targets/*.yaml
      refresh_interval: 60m

[root@localhost prometheus] systemctl restart prometheus
