Trigger for multiple items

[Ravzya]

Hello,

I would like to raise an alert with Zabbix when I receive several alerts for the same problem.
For example, several websites on the same server are inaccessible, how can I raise an alert to say that the host has a problem?

Is it possible with Zabbix in native mode ?

Thank you,
