Separando os logs do Bind

27 de setembro de 2013 Adonai Canêz Leave a comment

Na instalação padrão do Bind os logs do serviço são enviados para o syslog e por isso mistura com os logs dos outros serviços, o que dificulta muito para o administrador do Bind identificar possíveis problemas. Por isso eu adotei uma forma que separa cada tipo de categoria de mensagem em um arquivo diferente, dessa forma fica muito simples a visualização dos logs e a manipulação deles por scripts.

Abaixo tem um exemplo da separação que eu fiz, as categorias diferem entre as versões do Bind por isso ao criar essa configuração vale a pena baixar o Manual do Bind, no site da ISC https://www.isc.org/downloads/bind/ e verificar a seção “logging” para identificar as categorias disponíveis na sua versão do Bind.
