scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["10.0.0.200:9090"]
  ## 在下方添加自动发现的对应的文件
  - job_name: "prome_file_sd"   ##在prometheus网页中组名
    file_sd_configs:
    - files:
      - /app/prometheus/file_sd/agent.yml    ## 指定自动发现的文件
      refresh_interval: 5s				    ##  更新自动发现的时间
