Boa Leo
Pricipalmente se voce testou o script com root, o arquivo que vc está usando
no /tmp para calculos pode não estar com direitos de escrita para o Nagios.
Outra dica é tentar fazer o script "reentrante", isto é, que seja possivel
varias copias do mesmo rodando ao mesmo tempo. como voce usou um nome de
arquivo fixo para armazenamento temporario, pode dar pau. Recomendo que voce
coloque a variavel $$ compondo o nome do arquivo (numero do processo shell
que roda o script) e, ao final, remova este arquivo. Algo do tipo
/tmp/nome.temp.$$
