Re: Problemas Nagios * Exibir Resposta*

Luis

Na saída do seu script, quando está testando se o resultado obtido é OK,
WARNING ou CRITICAL, o script deve terminar com exit 0, 1 ou 2 conforme a
situação estiver OK, WARNING ou CRITICAL...

Quanto ao null, veja se o script retorna somente uma linha. O Nágios só
mostra na interface uma linha, mesmo que ela seja relativamente grande. Se
for grande, o browser se encarrega de quebrá-la...
