+# Implementação de Monitoramento e Alertas
+
+## Visão Geral
+
+Este documento descreve a implementação de um sistema completo de monitoramento e alertas para o Portal Jurunense API, baseado em Prometheus, Grafana e AlertManager. O sistema permite visualizar métricas de performance, configurar dashboards personalizados e receber alertas automáticos quando ocorrerem problemas.
+
+## Componentes Implementados
+
+### 1. Coleta de Métricas
+
+#### Métricas da API
+- **HTTP**: Requisições, duração, códigos de status
+- **Recursos**: Uso de CPU, memória, disco
+- **Banco de Dados**: Conexões de pool, duração de queries
+- **Negócio**: Métricas específicas do domínio (pedidos, pagamentos, etc.)
+
+#### Implementação
+- Integração com `@willsoto/nestjs-prometheus`
+- Endpoint `/metrics` exposto para scraping do Prometheus
+- Interceptor para coleta automática de métricas HTTP
+- Serviço personalizado para métricas de negócio
+
+### 2. Dashboards Grafana
+
+#### Dashboard Principal
+![Dashboard Principal](https://via.placeholder.com/800x400?text=Portal+Jurunense+Main+Dashboard)
+
+**Painéis Incluídos:**
+- Visão geral da saúde da aplicação
+- Taxa de requisições por segundo
+- Latência das requisições (percentis)
+- Uso de recursos (CPU, memória, disco)
+- Taxa de erros HTTP
+
+#### Dashboard de Banco de Dados
+![Dashboard de Banco de Dados](
+
+**Painéis Incluídos:**
+- Uso do pool de conexões
+- Tempo de resposta de queries
+- Queries em execução
+- Erros de banco de dados
+- Saúde das conexões
+
+#### Dashboard de Negócio
+![Dashboard de Negócio]
+
+**Painéis Incluídos:**
+- Pedidos por hora/dia
+- Taxa de conversão de pagamentos
+- Erros de processamento
+- Tempo de resposta de APIs externas
+- Alertas ativos
+
+### 3. Sistema de Alertas
+
+#### Alertas Implementados
+- **Disponibilidade**: Serviço fora do ar
+- **Performance**: Tempo de resposta elevado
+- **Recursos**: Uso elevado de memória, CPU ou disco
+- **Banco de Dados**: Pool de conexões quase esgotado
+- **Negócio**: Erros de integração com serviços externos
+
+#### Canais de Notificação
+- **Email**: Para alertas não críticos e relatórios diários
+- **Slack**: Para alertas em tempo real, com cores baseadas na severidade
+- **Microsoft Teams**: Alternativa para organizações que usam Teams
+- **SMS/Chamada** (opcional): Para alertas críticos fora do horário comercial
+
+### 4. Arquitetura de Monitoramento
+

+                   └────────────┘    └─────────────┘
+```
+
+## Configuração e Uso
+
+### Iniciando o Sistema de Monitoramento
+
+```bash
+# Iniciar todos os serviços de monitoramento
+docker-compose -f docker-compose.monitoring.yml up -d
+
+# Verificar status dos serviços
+docker-compose -f docker-compose.monitoring.yml ps
+
+# Visualizar logs
+docker-compose -f docker-compose.monitoring.yml logs -f
+```
+
+### Acessando as Interfaces
+
+- **Prometheus**: http://localhost:9090
+- **Grafana**: http://localhost:3000 (admin/admin)
+- **AlertManager**: http://localhost:9093
+
+### Customizando Alertas
+
+1. Edite o arquivo `monitoring/prometheus/rules/portaljuru_alerts.yml`
+2. Adicione ou modifique regras de alerta usando a sintaxe PromQL
+3. Recarregue a configuração: `curl -X POST http://localhost:9090/-/reload`
+
+### Customizando Dashboards
+
+1. Acesse o Grafana: http://localhost:3000
+2. Faça login com as credenciais padrão (admin/admin)
+3. Navegue até Dashboards > Browse
+4. Clone um dashboard existente ou crie um novo
+5. Use o editor visual para adicionar painéis e consultas
+
+## Integração com APM (Application Performance Monitoring)
+
+Além do monitoramento baseado em métricas, implementamos integração com ferramentas de APM para rastreamento distribuído e profiling:
+
+### Jaeger para Rastreamento Distribuído
+
+- **Endpoint**: http://localhost:16686
+- **Features**:
+  - Visualização de traces completos de requisições
+  - Análise de gargalos em calls entre serviços
+  - Rastreamento de erros e exceções
+
+### Configuração de Rastreamento Distribuído
+
+O código abaixo foi adicionado para habilitar o rastreamento:
+
+```typescript
+// Trecho simplificado. O código completo está no módulo de saúde.
+import { TracingModule } from './tracing.module';
+
+@Module({
+  imports: [
+    TracingModule.forRoot({
+      serviceName: 'portaljuru-api',
+      samplingRate: 0.3, 
+    }),
+    // ...
+  ],
+})
+export class AppModule {}
+```
+
+## Monitoramento Proativo
+
+Implementamos monitoramento proativo através de:
+
+1. **Health Checks Periódicos**: Verificações automáticas a cada 5 minutos
+2. **Alertas Preditivos**: Baseados em tendências anômalas de métricas
+3. **Relatórios Diários**: Resumo automático enviado diariamente por email
+4. **Página de Status**: Disponível em `/health/status` para usuários finais
+
+## Boas Práticas
+
+1. **Métricas Relevantes**: Foco em métricas que refletem a experiência do usuário
+2. **Alertas Acionáveis**: Somente alertar em situações que precisam de ação humana
+3. **Redução de Ruído**: Agrupamento e correlação de alertas para evitar fadiga
+4. **Documentation as Code**: Dashboards e regras de alerta versionadas no git
+5. **Runbooks**: Documentação de resposta para cada tipo de alerta
+
+## Próximos Passos
+
+1. **Expandir Métricas de Negócio**: Adicionar KPIs específicos para cada domínio
+2. **Machine Learning**: Implementar detecção de anomalias baseada em ML
+3. **Logs Centralizados**: Integrar com ELK Stack para correlação logs-métricas
+4. **SLOs e SLIs**: Definir e monitorar objetivos de nível de serviço
+5. **Automação de Remediação**: Scripts para resposta automática a problemas comuns
+
+## Conclusão
+
+O sistema de monitoramento implementado proporciona visibilidade completa sobre a saúde e performance do Portal Jurunense API. Com dashboards intuitivos e alertas precisos, a equipe pode detectar e resolver problemas rapidamente, reduzindo o tempo médio de recuperação (MTTR) e melhorando a confiabilidade do serviço.
