Start Zabbix Server(2) when the principal Zabbix Server is down

[Pablo116d]

Hello,
this is my first post on Zabbix Forums but I read some post everyday to help my zabbix server.

So, I have two ZabbixServer, both are the same because the second is a back up. So I need to configure something (I think its a trigger) that when the principal ZabbixServer goes down (Zabbix Server is down), the other automatically start up keeping the monitoring up.

Any help is allowed.

Thanks!
