查看集群

1. 查看集群健康

1
curl -X GET "localhost:9200/_cat/health?v"

2. 查看集群节点

1
curl -X GET "localhost:9200/_cat/nodes?v"

3. 查看集群所有索引

1
curl -X GET "localhost:9200/_cat/indices?v"

get 获取指定数据

1. 直接获取数据

1
curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/AWSudIFgTuj3oZBEhyxK?pretty"

格式为 /{index}/{type}/{id}

字段 含义
monitor_log_mch_order_out 索引 (_index)
logs 索引的类型 (_type), 不知道类型可以用 _all 匹配
AWSudIFgTuj3oZBEhyxK id (_id)
pretty json格式显示数据, 可省略

2. 屏蔽或只查看 _source

1
curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/AWSudIFgTuj3oZBEhyxK?pretty&_source=false"

添加 _source=false 即可

1
curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/AWSudIFgTuj3oZBEhyxK/_source?pretty"

3. 过滤字段

1
curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/AWSudIFgTuj3oZBEhyxK?pretty&_source_include=log*&_source_exclude=logType"

获取包含 log* 且不为 logType 的字段

1
curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/AWSudIFgTuj3oZBEhyxK?pretty&_source=logType,logLevel"

只查询指定字段的简易写法

mget 多条件匹配查询

  1. 匹配多个索引, 同时查询多个id的数据

    curl -X GET "localhost:9200/_mget?pretty" -H 'Content-Type: application/json' -d'
    {
        "docs" : [
            {
                "_index" : "monitor_log_mch_order_out",
                "_type" : "logs",
                "_id" : "AWSudIFgTuj3oZBEhyxK"
            },
            {
                "_index" : "monitor_log_mch_order_out",
                "_type" : "logs",
                "_id" : "AWSuXewETuj3oZBEhywS"
            }
        ]
    }
    '

  2. 可以将索引写在host后面, 代表查询的都为同一索引下的数据

    curl -X GET "localhost:9200/monitor_log_mch_order_out/_mget?pretty" -H 'Content-Type: application/json' -d'
    {
        "docs" : [
            {
                "_type" : "logs",
                "_id" : "AWSudIFgTuj3oZBEhyxK"
            },
            {
                "_type" : "logs",
                "_id" : "AWSuXewETuj3oZBEhywS"
            }
        ]
    }
    '

  3. 合并index和type, 代表查询的都为同一索引下type也相同的数据

    1

    6
    7
    8

    curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/_mget?pretty" -H 'Content-Type: application/json' -d'
    {
        "docs" : [
            {
                "_id" : "AWSudIFgTuj3oZBEhyxK"
            },
            {
                "_id" : "AWSuXewETuj3oZBEhywS"
            }
        ]
    }
    '

    简化后如下:

    1

    3
    4
    5
    curl -X GET "localhost:9200/monitor_log_mch_order_out/logs/_mget?pretty" -H 'Content-Type: application/json' -d'
    {
    	"ids" : ["AWSudIFgTuj3oZBEhyxK", "AWSuXewETuj3oZBEhywS"]
    }
    '

注: 当多个条件的 _type 相同时 可以使用 _all 或者省略

  1. 过滤字段, 每个Id分别对 _source进行过滤

            {
                "_id" : "AWSudIFgTuj3oZBEhyxK",
                "_source" : false
            },
            {
                "_id" : "AWSuXewETuj3oZBEhywS",
                "_source" : ["bizId", "method"]
            },
            {
                "_id" : "AWSuLAYqTuj3oZBEhysH",
                "_source" : {
                    "include": ["log*"],
                    "exclude": ["logLevel"]
                }
            }
        ]
    }
