Sorry, I don' t speak english, but a will try write my doubt.
I have 2 hosts and they are the same configuration, service definition and host definition.
Both hosts are down, but when I start nagios I received notification only to 1 host.
I configured my contact for send telegram.
I would like to know, why I am receiving just one message if the 2 hosts are down.
Follow the files that I used for my configuration:
Configuration of hosts1

use linux-server ; Name of host template to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.
