Bom artigo, ótima ferramenta.

Lembra muito uma ferramenta de monitoramento, desenvolvida pela Constat (www.constat.com.br) com base no Nagios.

Celfs,

O host que está querendo monitorar está respondendo a pacotes ICMP enviados de dentro do servidor Nagios?

celfs,

Ao concluir a instalação do centreon, automaticamente ele começa a monitorar o localhost(127.0.0.1), isso aconteceu quando você terminou a instalação?
