Integração Postfix

Instalar o agente de infraestrutura

Para usar a integração do Postfix, você também precisa instalar o agente de infraestrutura no mesmo host. O agente de infraestrutura monitora o próprio host, enquanto a integração que você instalará na próxima etapa amplia seu monitoramento com dados específicos do Postfix.

Exportar dados Postfix

Exporte sua métrica Postfix com pflogsumm. O agente Postfix usapflogsumm como analisador log , que se traduz em dados métricos sobre sua atividade Postfix. Isso fornece detalhes suficientes para antecipar possíveis incidentes com administração de e-mail.

Siga estas etapas para usar pflogsumm.

1. Execute os seguintes comandos para fazer download e extrair pflogsumm:

   bash

   Copiar

   $
   wget https://jimsun.linxnet.com/downloads/pflogsumm-1.1.3.tar.gz

   bash

   Copiar

   $
   tar xvf pflogsumm-1.1.3.tar.gz

2. Vá para a pasta pflogsumm .

   bash

   Copiar

   $
   cd pflogsumm-*.*.*

3. Copie o arquivo pflogsumm.pl para o caminho /usr/local/bin/pflogsumm :

   bash

   Copiar

   $
   sudo cp pflogsumm.pl  /usr/local/bin/pflogsumm

4. Execute os seguintes comandos pflogsumm para exportar a métrica do Postfix:

   bash

   Copiar

   $
   cat /var/log/mail.log | pflogsumm
   $
   cat /var/log/mail.log | pflogsumm -d today

Configurar NRI-Flex para Postfix

Flex, nossa ferramenta de monitoramento aplicativo agnóstico, vem junto com o agente New Relic Infrastructure . Siga estas etapas para criar um arquivo de configuração flexível para seus dados Postfix:

1. Crie um arquivo chamado postfix-flex-config.yml:

   bash

   Copiar

   $
   touch /etc/newrelic-infra/integrations.d/postfix-flex-config.yml

2. Atualize o arquivo postfix-flex-config.yml. Recomendamos que você trabalhe com nosso exemplo de configuração abaixo:

   Copiar

   Se você preferir fazer o seu próprio, certifique-se de que seu arquivo yaml siga o padrão acima. Edite o seguinte atributo conforme necessário:

• EVENT_TYPE: Uma tabela de banco de dados New Relic que você pode consultar usando NRQL.
• COMMAND: O comando usado para imprimir métricas no terminal.

Encaminhe seu log do Postfix para o New Relic

Siga estas etapas para encaminhar o log do Postfix para New Relic:

1. Crie um arquivo denominado logging.yml no diretório do agente de infraestrutura:

   bash

   Copiar

   $
   touch /etc/newrelic-infra/logging.d/logging.yml

2. Adicione o seguinte trecho ao arquivo logging.yml :

   logs:
     - name: mail.log
       file: /var/log/mail.log
       attributes:
         logtype: postfix_maillog

   Copiar

Reinicie o agente de infraestrutura

Use as instruções em nossos documentos do agente de infraestrutura para reiniciar seu agente de infraestrutura. Este é um comando básico que deve funcionar para a maioria das pessoas:

$
sudo systemctl restart newrelic-infra.service
