 `harbor_traffic_bytes_total` содержит общий накопленный объём по источникам Gateway/Proxy. `harbor_device_traffic_bytes_total` содержит upload/download по стабильному `device_id`; пользовательское название и текущий IP находятся в `harbor_device_info`. `harbor_device_domain_traffic_bytes_total` добавляет наблюдённые домен, сервис, источник и направление для каждого устройства. `harbor_domain_traffic_attribution_events_total{outcome}` помогает отличить нераспознанный hostname, неизвестное устройство и неподдерживаемый inbound без динамических high-cardinality labels.
 
-Dashboard отделяет текущую скорость от значений за выбранный период и накопленных счётчиков. Единый фильтр `Устройства` по умолчанию охватывает все устройства, но позволяет выбрать одно; список показывает `name · ip`, сохраняя стабильный `device_id` как значение. Он управляет графиками скорости, накопленным трафиком, сервисами и доменами. Отдельный график скорости по устройствам показывает одну суммарную линию на каждое активное устройство; нулевые устройства и source/direction series скрыты. Top-10 устройств за период отсортирован по убыванию и выбирает устройство в том же фильтре. Domain table показывает только сервис, домен и трафик. Автообновление настроено на 30 секунд; freshness предупреждает после 60 секунд и считает данные устаревшими после 120 секунд.
+Фактический выход экспортируется отдельно. `harbor_singbox_tracked_bytes_total{source,outbound,direction}` показывает наблюдённые sing-box байты с `outbound="vpn|direct|unknown"`; вариант с префиксом `harbor_device_...` добавляет `device_id`. `harbor_direct_ipv4_packet_bytes_total{direction}` считает IPv4-пакеты, которые Gateway направил напрямую вместо sing-box, включая policy Direct и работу при остановленном VPN runtime; вариант `harbor_device_...` содержит атрибутированную детализацию. `source="gateway|proxy"` по-прежнему означает место входа, а `outbound` — выбранный sing-box выход.
 
-Domain counters снимаются с активных соединений sing-box раз в 2 секунды и хранятся в памяти dataplane до его перезапуска; историю и retention хранит Prometheus. Перед routing sing-box до 1 секунды распознаёт HTTP Host, TLS SNI и QUIC Server Name. YouTube и OpenAI / ChatGPT объединяются по известным связанным доменам в label `service`, остальные значения сохраняют домен как имя сервиса. Если устройство и Harbor source известны, но hostname недоступен (например, ECH или IP-only), трафик попадает в `domain="_unknown",service="Не распознано"` и не теряется. Новые domain series сверх process limit складываются в `_other`. В метрики не входит физический трафик вне Harbor, устройства с policy Direct, соединения между двумя снимками и байты после последнего снимка перед закрытием или quota провайдера.

+Direct IPv4 считает L3 packet bytes с IP-заголовками и retransmit, а sing-box tracker — логические TCP/UDP bytes без tunnel overhead. Эти семейства нельзя складывать в один «точный общий трафик». Snapshot polling может пропустить короткие соединения и финальный хвост; IPv6, трафик вне Gateway, назначения из `BYPASS_CIDRS` и quota провайдера не входят в новый route split.
 
 Готовый dashboard: [`monitoring/grafana/harbor-gateway.json`](monitoring/grafana/harbor-gateway.json). При импорте Grafana попросит выбрать Prometheus data source. Та же конфигурация и dashboard доступны для копирования в Gateway drawer «Как использовать» → «Prometheus и Grafana».
