Componentes: - tempo-values.yaml: Grafana Tempo monolithic, 256Mi, 10Gi PVC - otel-collector-values.yaml: recebe OTLP, exporta traces→Tempo, gera span metrics (RED)→Victoria Metrics via spanmetrics connector - demo-app/: Node.js com rotas /fast (1 query), /slow (N+1, 51 queries), /fixed (JOIN), auto-instrumentado com OpenTelemetry - alerts/latency-alerts.yaml: VMRule com Doherty threshold (p95>400ms) - setup.sh: instala Tempo, OTel Collector, configura Grafana datasource, deploy demo app via ConfigMap (sem Docker build necessário) - cleanup.sh: remove apenas recursos da aula-15, preserva aula-12 Zero hardcoded hostnames. Tudo via .env e placeholders.
