Boa noite,
Pessoal gostaria de receber alguma dica para deixar o nagios checando
instântaneo pois quando um host
cai, demora cerca de 10minutos para atualizar que o host está down e isso vem
me causando problemas
pois tenho que praticamente monitorar a ferramenta de monitoramento.
Segue abaixo meu arquivo de configuração
nagios.cfg
