Description:
I configured mail notifications for my whole team. Unfortunately if for example the firewall of site A is offline we receive a bunch of mails for every system in the site which the corresponding state (down/unreachable).
What I would expect is that only the notification for the parent host will be triggered and the child hosts will get unreachable but there shouldn’t be a notification about that state change (up → unreachable).
That is my current notification rule.
I know I could just enable match host event type and untick state change up → unreachable, but in the docs it is mentioned that it should suppress unreachable notifications automatically and I would like to understand the logic behind correctly:
