Все три Go-сервиса (ingest, device-control, rule-engine) отдают /metrics в формате Prometheus: счётчики MQTT/RabbitMQ/ClickHouse операций, гистограммы длительности батч-флашей и диспатча правил, переходы устройств online/offline. Добавлены сервисы prometheus и grafana в docker-compose с провижининг конфигом (datasource + два готовых дашборда: "Ingest & Telemetry" и "Automation & Devices").
