IP范围聚合 ip_range

IP Range Aggregation

GET /ip_addresses/_search
{
    "size": 10,
    "aggs" : {
        "ip_ranges" : {
            "ip_range" : {
                "field" : "ip",
                "ranges" : [
                    { "to" : "10.0.0.5" },
                    { "from" : "10.0.0.5" }
                ]
            }
        }
    }
}

返回

{
    ...

    "aggregations": {
        "ip_ranges": {
            "buckets" : [
                {
                    "key": "*-10.0.0.5",
                    "to": "10.0.0.5",
                    "doc_count": 10
                },
                {
                    "key": "10.0.0.5-*",
                    "from": "10.0.0.5",
                    "doc_count": 260
                }
            ]
        }
    }
}

IP范围也可以定义为CIDR掩码：

GET /ip_addresses/_search
{
    "size": 0,
    "aggs" : {
        "ip_ranges" : {
            "ip_range" : {
                "field" : "ip",
                "ranges" : [
                    { "mask" : "10.0.0.0/25" },
                    { "mask" : "10.0.0.127/25" }
                ]
            }
        }
    }
}

返回

{
    ...

    "aggregations": {
        "ip_ranges": {
            "buckets": [
                {
                    "key": "10.0.0.0/25",
                    "from": "10.0.0.0",
                    "to": "10.0.0.128",
                    "doc_count": 128
                },
                {
                    "key": "10.0.0.127/25",
                    "from": "10.0.0.0",
                    "to": "10.0.0.128",
                    "doc_count": 128
                }
            ]
        }
    }
}

Keyed

将keyed标志设置为true会将一个唯一的字符串键与每个bucket相关联，并将范围作为哈希而不是数组返回：

GET /ip_addresses/_search
{
    "size": 0,
    "aggs": {
        "ip_ranges": {
            "ip_range": {
                "field": "ip",
                "ranges": [
                    { "to" : "10.0.0.5" },
                    { "from" : "10.0.0.5" }
                ],
                "keyed": true
            }
        }
    }
}

返回

{
    ...

    "aggregations": {
        "ip_ranges": {
            "buckets": {
                "*-10.0.0.5": {
                    "to": "10.0.0.5",
                    "doc_count": 10
                },
                "10.0.0.5-*": {
                    "from": "10.0.0.5",
                    "doc_count": 260
                }
            }
        }
    }
}

还可以自定义每个范围的key：

GET /ip_addresses/_search
{
    "size": 0,
    "aggs": {
        "ip_ranges": {
            "ip_range": {
                "field": "ip",
                "ranges": [
                    { "key": "infinity", "to" : "10.0.0.5" },
                    { "key": "and-beyond", "from" : "10.0.0.5" }
                ],
                "keyed": true
            }
        }
    }
}

返回

{
    ...

    "aggregations": {
        "ip_ranges": {
            "buckets": {
                "infinity": {
                    "to": "10.0.0.5",
                    "doc_count": 10
                },
                "and-beyond": {
                    "from": "10.0.0.5",
                    "doc_count": 260
                }
            }
        }
    }
}
