修改 Prometheus 配置

scrape_configs下新增job_name为elasticsearch（名称随意）

  - job_name: 'elasticsearch'
    static_configs:
      - targets: ['192.168.0.100:9114']

完整的scrape_configs如下

scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
  - job_name: 'elasticsearch'
    static_configs:
      - targets: ['192.168.0.100:9114']
