Existe uma interface do kernel Linux (/proc) que conta mensagens de log de erros do kernel?

  • 772

O comando dmesg --level=emerg,alert,crit,errlista todas as mensagens de erro com alta gravidade.

Fiquei pensando, para fins de monitoramento, se a contagem de mensagens é de alguma forma exposta no /procsistema de arquivos. Seria ótimo dar uma indicação de problemas de hardware.

    Não, não há nada disso.

    dmesg --level=emerg,alert,crit,errvs "Seria ótimo dar uma indicação dos problemas de hardware."

    Mensagens nesses níveis de log não são necessariamente indicativas de problemas de hardware.

    Aqui está o que eu recebo:
