I want a function that not will sending me 10 copys of false positive e-mails every time it just happen something with one agent.

For example one agent goes down and it start sending ICMP alarm even if the first trigger has failed.

I know about the Depends on function but i looking for something similar to icinga2 Flapping detection support.
