# Trechos de modelo do Amazon CloudWatch Logs
O Amazon CloudWatch Logs pode monitorar seu sistema, aplicativos e arquivos de log personalizados em instâncias do Amazon EC2 ou outras origens. Você pode usar o CloudFormation para provisionar e gerenciar grupos de logs e filtros de métricas. Para obter mais informações sobre o CloudWatch Logs, consulte o [Guia do usuário do Amazon CloudWatch Logs](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html).

## Enviar logs para o CloudWatch Logs de uma instância do Linux
O modelo a seguir demonstra como configurar um servidor Web no Amazon Linux 2023 com a integração com o CloudWatch Logs. O modelo executa as seguintes tarefas:
+ Instala o Apache e o PHP.
+ Configura o agente do CloudWatch para encaminhar logs de acesso do Apache para o CloudWatch Logs.
+ Configura um perfil do IAM para permitir que o agente do CloudWatch envie dados de log ao CloudWatch Logs.
+ Cria alarmes e notificações personalizados para monitorar erros 404 ou alto uso de largura de banda.
Os eventos de logs do servidor Web fornecem dados de métricas para os alarmes do CloudWatch. Os dois filtros de métrica descrevem como as informações de log são transformadas em métricas do CloudWatch. A métrica 404 conta o número de ocorrências 404. A métrica de tamanho controla o tamanho de uma solicitação. Os dois alarmes do CloudWatch enviarão notificações se houver mais que duas 404s em 2 minutos ou se o tamanho médio da solicitação for superior a 3500 KB por 10 minutos.

## Enviar logs para o CloudWatch Logs de uma instância do Windows
O modelo a seguir configura o CloudWatch Logs para uma instância do Windows 2012R2.
O agente do CloudWatch Logs no Windows (agente SSM em AMIs do Windows 2012R2 e Windows 2016) só envia os logs depois que ele é iniciado, de maneira que os logs gerados antes da inicialização não são enviados. Para resolver isso, o modelo ajuda a garantir que o agente inicie antes que qualquer log seja gravado ao:
+ Configurar o agente como o primeiro item `config` no `configSets` do cfn-init.
+ Usar o `waitAfterCompletion` para inserir uma pausa depois do comando que inicia o agente.
