Monitoramento de serviço através de reator de sal e beacon

Question

Eu tento monitorar o serviço através de reator de sal e beacon. Se o evento acontecer (por exemplo: parada do serviço nginx em um lacaio), é necessário gravá-lo em um arquivo no mestre de sal.

Não tenho ideia de como chamar os dados do evento e passá-los para write_file.sls . Alguém pode me ajudar?

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

O arquivo /srv/salt/monitoring/9spokesBeaconN.sls :

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

O arquivo 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 }}
