Limpieza de la configuración de Alloy eliminando componentes no utilizados: Métricas (Prometheus): - Mantiene scraping de: Alloy, Prometheus, Grafana, Loki, app_metrics - Comentados: Tempo, Node Exporter, cAdvisor - Receptor HTTP para métricas externas (puerto 9999) - Remote write a Prometheus Logs (Loki): - Descubrimiento y recolección de logs de contenedores Docker - Receptor HTTP para logs externos (puerto 3101) - Receptor Syslog (puerto 1514) - Envío a Loki Trazas: - Sección completa de Tempo comentada (OTLP, Jaeger, Zipkin) La configuración resultante está enfocada exclusivamente en métricas y logs, reduciendo la superficie de ataque y simplificando el troubleshooting.
