As notificações automáticas do Nagios 3.5.0 (no Ubuntu) parecem não funcionar e o erro dado é "Nenhum contato foi encontrado para fins de notificação. Nenhuma notificação foi enviada". O abaixo pode ser encontrado no log de depuração:

Verificando a configuração Não vejo nenhum problema:

Um estranho é que as notificações personalizadas funcionam:
[1370347216.906200] [032.0] [pid=30297] ** Service Notification Attempt ** Host: 'nbsrvcomp-11', Service: 'Number open file descriptors', Type: 99, Options: 0, Current State: 1, Last Notification: Thu Jan 1 01:00:00 1970

Qualquer ajuda será muito apreciada.
O problema é que você definiu o contato com todas as opções:
host_notification_options d,u,r,f,s,n
service_notification_options w,u,c,r,f,s,n
e entre eles, é a opção n (nenhum). Então você não recebeu nenhuma notificação.
Remova a opção n do host e notificação de serviço em contato e problema resolvido.
Acho que contactgroups deve ser contact_groups
