Observabilidade OpenTelemetry para Next.js

Configure, teste e verifique a observabilidade com OpenTelemetry (OTel) em aplicações Next.js App Router. A habilidade é acionada pelos comandos "/nextjs-otel", "setup otel", "configure opentelemetry", "test otel" ou "verify opentelemetry".

O que é Observabilidade OpenTelemetry para Next.js?

Esta habilidade fornece um fluxo de trabalho modular e pronto para produção para configurar, testar e verificar o tracing com OpenTelemetry em aplicações Next.js que utilizam o App Router. Ela padroniza o uso de uma única chave de interrupção (`OTEL_SDK_DISABLED`) para controlar a ativação do tracing, protegendo contra bugs conhecidos de avaliação de booleanos em strings na biblioteca `@vercel/otel`. A habilidade automatiza a criação do arquivo `instrumentation.ts`, a instalação das dependências necessárias e a configuração das variáveis de ambiente. Além disso, inclui um harness de teste com um coletor OTLP simulado para verificar tanto o funcionamento ativo do tracing quanto o comportamento da chave de interrupção, gerando um relatório de verificação em Markdown. É compatível com projetos Next.js que usem `pnpm`, `npm` ou `bun` e segue as melhores práticas de arquitetura para evitar violações de limites de runtime e configurações conflitantes.

Habilidade de Observabilidade OpenTelemetry para Next.js (nextjs-otel)

Um fluxo de trabalho modular e pronto para produção para configurar, testar e verificar o tracing OpenTelemetry em aplicações Next.js App Router, padronizando o uso de uma única chave de interrupção, protegendo contra bugs de inicialização do @vercel/otel e automatizando a verificação de traces.

Manual de Execução Passo a Passo

Siga esta lista de verificação sequencialmente para configurar e verificar a observabilidade OpenTelemetry:

1. Descoberta do Projeto e Inspeção de Dependências

  • Inspecionar Estrutura do Projeto: Confirmar a versão do Next.js App Router no package.json e o gerenciador de pacotes (pnpm, bun, npm).
  • Localizar Raiz da Instrumentação: Verificar se o projeto usa o arquivo raiz instrumentation.ts ou src/instrumentation.ts.
  • Revisar Padrões Arquiteturais: Consultar architectural-standards.md para disciplina de chave de interrupção única e limites de runtime.

2. Instalação de Dependências

  • Instalar Pacotes Principais de Telemetria:
    pnpm add @vercel/otel @opentelemetry/api
    

3. Implantar instrumentation.ts

  • Criar Arquivo de Instrumentação: Implantar instrumentation.ts.template na raiz ou em src/.
  • Aplicar Salvaguarda de Veracidade: Garantir que register() remova process.env.OTEL_SDK_DISABLED quando não for estritamente "true" para evitar bugs de avaliação booleana do @vercel/otel.
  • Vincular Rastreamento de Erros: Garantir que onRequestError() capture next.error.digest, o caminho da rota e metadados HTTP nos spans ativos.

4. Configurar Variáveis de Ambiente

  • Atualizar Templates de Ambiente: Injetar configuração OpenTelemetry em .env.example e .env.local usando env.otel.template.
  • Definir Nome do Serviço e Protocolo: Configurar OTEL_SERVICE_NAME, OTEL_EXPORTER_OTLP_ENDPOINT e OTEL_EXPORTER_OTLP_PROTOCOL=http/json.

5. Verificação e Teste

  • Iniciar Coletor OTLP Simulado: Iniciar o coletor de teste na porta 4318 conforme verification-and-testing.md:
    node .agents/skills/nextjs-otel/scripts/mock_collector.js
    
  • Verificar Traces Ativos (OTEL_SDK_DISABLED=false): Disparar requisições de teste (curl http://localhost:3000/) e verificar lotes POST /v1/traces com HTTP 200 OK.
  • Verificar Chave de Interrupção (OTEL_SDK_DISABLED=true): Confirmar que o servidor Next.js registra [OTel] Instrumentation hook skipped e exporta 0 traces.
  • Gerar Relatório de Verificação: Produzir relatório resumido em Markdown.

Casos Extremos e Armadilhas Conhecidas de IA

[!WARNING]

  • O Bug de Veracidade de String do @vercel/otel: O @vercel/otel avalia !!process.env.OTEL_SDK_DISABLED. Em JavaScript, Boolean("false") é true. Sem remover process.env.OTEL_SDK_DISABLED quando não for 'true', definir OTEL_SDK_DISABLED=false desativa o tracing silenciosamente.
  • Flags Personalizadas Secundárias: Nunca introduzir OTEL_ENABLED junto com OTEL_SDK_DISABLED. Padronizar estritamente em OTEL_SDK_DISABLED.
  • Violações de Limites de Runtime: Nunca importar instrumentation.ts ou SDKs OpenTelemetry do servidor em Componentes Cliente ("use client").
  • Comandos Encadeados: Nunca encadear comandos (&&, ||, ;). Executar todos os comandos de configuração e teste individualmente.

Esquema de Resumo de Saída

Após concluir a configuração ou verificação do OpenTelemetry, gerar um relatório estruturado:

# Relatório de Verificação OpenTelemetry
