Hi)
How to setting notifications for only send when host down and up
TY
Icinga has two types of notification: host and service.
You clearly want to enable host notifications and not service notifications.
See
https://icinga.com/docs/icinga-2/latest/doc/03-monitoring-basics/#notifications
https://icinga.com/docs/icinga-2/latest/doc/04-configuration/#notificationsconf
for more detail on setting this up.
