Prometheus cAdvisor - Как мне увидеть метрики для контейнеров, а не для хоста

Я следую этому руководству, чтобы настроить cadvisor + prometheus + Grafana для мониторинга контейнеров докеров. Все выглядит нормально, за исключением того, что я не могу найти метрики на уровне контейнера (метрики хоста отображаются нормально). Например, если я получу «container_memory_cache» в Prometheus, он вернет следующие результаты:

container_memory_cache{id="/",instance="cadvisor:8080",job="cadvisor"}

Измерение "id" равно нулю, и измерение "name" отсутствует. Проверив больше, я попытался запустить остальные API cAdvisor для получения информации о контейнере, используя идентификатор / имя контейнера, но все равно не повезло:
