Eu verifico meu servidor na WAN com ping e https pelo Nagios Core 3.5.1. Aqui está o histórico de alertas do host.

Então, às 17:29 horas estava tudo bem. 17:58 horas até 18:05 horas foi perda de pacotes = 100% e tempo limite de soquete.
Minha pergunta é: por que eu não recebi uma notificação?
Alguns dias antes e hoje recebo notificações de "aviso" muito bem, mas nunca recebo uma notificação "crítica".
Aqui está o meu contact.cfg
define contact{
contact_name nagiosadmin ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user
email user@localhost ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
}
Aqui está meu templates.cfg
define contact{
name generic-contact ; The name of this contact template
service_notification_period 24x7 ; service notifications can be sent anytime
host_notification_period 24x7 ; host notifications can be sent anytime
service_notification_options w,u,c,r,f,s ; send notifications for all service states, flapping events, and scheduled downtime events
host_notification_options d,u,r,f,s ; send notifications for all host states, flapping events, and scheduled downtime events
service_notification_commands notify-service-by-email ; send service notifications via email
host_notification_commands notify-host-by-email ; send host notifications via email
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMPLATE!
}
Você não recebeu notificações porque todos os estados relatados são SOFT . As notificações são enviadas apenas para HARD states.
Você precisa examinar a configuração do serviço e verificar o valor de max_check_attempts para o seu serviço.
