通过盐堆和信标进行服务监控

Question

我尝试通过 salt react 和 beacon 来监控服务。如果发生事件（例如：nginx 服务在某个 minion 上停止），则需要将其写入 salt master 中的文件。

我不知道如何调用事件数据并将其传递给write_file.sls。有人能帮助我吗？

root@SALTMASTERLOCAL:/var/log/salt# salt-run reactor.list
event:
    ----------
suffix:
    salt/reactors/manage/list
|_
  ----------
  salt/beacon/*/service/:
      - /srv/salt/monitoring/9spokesBeaconN.sls

文件/srv/salt/monitoring/9spokesBeaconN.sls：

load_service_monitoring:
  local.state.apply:
    - tgt: '*MASTER*'
    - arg:
      - monitoring.write_file
    - kwarg:
        new_minion: {{ data }}

文件monitoring/write_file.sls：

{% from "monitoring/9spokesBeaconN.sls" import new_minion %}

create /root/beacons_load.confvg file:
  file.append:
    - name: /root/beacons_load.confvg 
    - text: {{ new_minion }}

结果/输出：
