Sendmail integração

Instalar o agente de infraestrutura

Para usar a integração do Sendmail, você precisa primeiro 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 Sendmail.

Use NRI-Flex para capturar métricas

Flex permite capturar métricas do Apache Zookeeper. Ele vem junto com o agente New Relic Infrastructure que você instalou na etapa anterior.

1. Crie um arquivo chamado sendmail-flex-config.yml no caminho /newrelic-infra/integrations.d .

2. Atualize sendmail-flex-config.yml com o exemplo de configuração a seguir.

   Certifique-se de substituir as referências FAILED_MESSAGES_FILE_NAME pelo nome do seu arquivo. Para encontrar esse nome de arquivo, vá para /var/mail/ e verifique se há mensagens com falha no arquivo que foi criado.

    logtype: sendmail_error

Reinicie o agente do New Relic Infrastructure

Antes de começar a ler seus dados, use as instruções em nossos documentos do agente de infraestrutura para reiniciar seu agente de infraestrutura.

$
sudo systemctl restart newrelic-infra.service

Em alguns minutos, seu aplicativo enviará métricas para one.newrelic.com.

Encontre seus dados

Você pode escolher nosso modelo dashboard pré-construído chamado Sendmail para monitor sua métrica do aplicativo Sendmail. Siga estas etapas para usar nosso modelo dashboard pré-construído:

1. De one.newrelic.com, vá para a página
