一个示例的收集：收集数据库的机器，将机器分组为 dba；收集中间件的机器，将机器分组为 mw。

- labels:
    hostgroup: dba
    hostname: mysql-demo-01
  targerts:
    - 127.0.0.1:9100
    - 127.0.0.1:9256
    - ...

- labels:
    hostgroup: mw
    hostname: es-demo-01
  targerts:
    - 127.0.0.1:9100
    - 127.0.0.1:9256
    - ...

一个示例的告警：不填写告警通知对象，程序从 labels.hostgroup 获取告警组。

  - alert: CPU负载大于2Cores
    expr: node_load1 > (instance:node_cpus:count * 2) 
    for: 4m
    labels:
      severity: critical
      level: 3
    annotations:
      description: "主机 {{ $labels.hostname }} CPU负载 {{ $value }}"

PrometheusAlert 发送告警的时候，从 labels.hostgroup 获取主机组作为告警组，然后从 app.conf 中取得对应组的通知地址（wxurl, ddurl, fsurl, phone...），发送告警。

如果 labels.hostgroup 为空，则还是使用之前发送告警的逻辑。

这样是不是可行，有没有必要？
