[Question] network interfaces

I try to monitor the network interfaces of my containers, but I don't seem to find a way to match the networks with the statistics.

When I request the network attribute from a container, I get the following information:

"Networks": {
    "homeassistant_homeassistant_default": {
        "IPAMConfig": None,
        "Links": None,
        "Aliases": [
            "home-assistant",
            "2474d497ad47"
        ],
        "NetworkID": "5c35742d633cf58a6c5de9f9f65c76a16bc30426739c6926a40092ec7e753bfe",
        "EndpointID": "aa9a9b2790af3f53b3ae218ea4e245a1656e1153f728116f70deb3793edeb4ee",
        "Gateway": "172.19.0.1",
        "IPAddress": "172.19.0.10",
        "IPPrefixLen": 16,
        "IPv6Gateway": "",
        "GlobalIPv6Address": "",
        "GlobalIPv6PrefixLen": 0,
        "MacAddress": "02:42:ac:13:00:0a"
    },
    "web": {
        "IPAMConfig": None,
        "Links": None,
        "Aliases": [
            "home-assistant",
            "2474d497ad47"
        ],
        "NetworkID": "b81adc4a270b3b3318a81a929957a3ca2765fe6f8ba72e882eeeef1059329f1f",
        "EndpointID": "8b9a33e73d235a9729b04b8e9bc4044eda1c1a7b1e150da2a5ef5284b87541af",
        "Gateway": "172.29.0.1",
        "IPAddress": "172.29.0.7",
        "IPPrefixLen": 16,
        "IPv6Gateway": "",
        "GlobalIPv6Address": "",
        "GlobalIPv6PrefixLen": 0,
        "MacAddress": "02:42:ac:1d:00:07"
    }
}

But when I request the network statistics I get the following:

"networks": {
    "eth0": {
        "rx_bytes": 138585375,
        "rx_packets": 771669,
        "rx_errors": 0,
        "rx_dropped": 0,
        "tx_bytes": 323989695,
        "tx_packets": 813381,
        "tx_errors": 0,
        "tx_dropped": 0
    },
    "eth1": {
        "rx_bytes": 4789050,
        "rx_packets": 67862,
        "rx_errors": 0,
        "rx_dropped": 0,
        "tx_bytes": 94635930,
        "tx_packets": 63802,
        "tx_errors": 0,
        "tx_dropped": 0
    }
}

So how can I match ethx with one of the Networks?

No source file or test is identified in the issue. Start by comparing the container's network metadata with the Docker Engine API network-statistics response, then determine whether a stable interface-to-network mapping exists; done means documenting the mapping or clearly stating that it cannot be obtained.
