Christiano, Verifiquei no template generic-host aqui e tem uma diretiva chamada "first_notification_delay". Que você pode habilitar ou não. Veja a descrição dela abaixo, retirada do help do próprio Nagios. Por default, o generic-host vem sem esse delay, mas pode ser que o teu aí, ou mesmo o host específico, esteja com ela ativa. Se for o caso, coloque 0 (zero) nela e faça testes. Dê retorno se for isso mesmo. Veja abaixo:
################################ Host - first notification delay This directive is used to define the number of "time units" to wait before sending out the first problem notification when this host enters a non-UP state. Unless you've changed the interval_length directive from the default value of 60, this number will mean minutes. If you set this value to 0, Nagios will start sending out notifications immediately. Parameter name: first_notification_delay Required: no ################################ Dito -----Mensagem original----- De: Christiano Liberato [mailto:christianoliber...@gmail.com] Enviada em: quarta-feira, 28 de dezembro de 2011 13:53 Para: Unofficial Brazilian (Portuguese) Nagios Users List Assunto: Re: [Nagios-users-br] Diminuir tempo de envio de email no nagios O tempo de envio é praticamente instantâneo.
