我想列出ElasticSearch服务器上的所有索引。我试了一下:

curl -XGET localhost:9200/

但它给了我这个:

{
  "ok" : true,
  "status" : 200,
  "name" : "El Aguila",
  "version" : {
    "number" : "0.19.3",
    "snapshot_build" : false
  },
  "tagline" : "You Know, for Search"
}

我想要一个所有索引的列表..

列出索引+和列表一起显示其状态的最好方法之一是简单地执行下面的查询。

注意:最好使用Sense来获得正确的输出。

curl -XGET 'http://localhost:9200/_cat/shards'

示例输出如下所示。主要的优点是,它基本上显示了索引名称和它保存到的分片,索引大小和分片ip等

index1     0 p STARTED     173650  457.1mb 192.168.0.1 ip-192.168.0.1 
index1     0 r UNASSIGNED                                                 
index2     1 p STARTED     173435  456.6mb 192.168.0.1 ip-192.168.0.1 
index2     1 r UNASSIGNED                                                 
...

_stats命令提供了通过指定所需指标来自定义结果的方法。要获得索引,查询如下:

GET /_stats/indices

_stats查询的一般格式是:

/_stats
/_stats/{metric}
/_stats/{metric}/{indexMetric}
/{index}/_stats
/{index}/_stats/{metric}

指标在哪里:

indices, docs, store, indexing, search, get, merge, 
refresh, flush, warmer, filter_cache, id_cache, 
percolate, segments, fielddata, completion

作为对自己的练习,我写了一个小的elasticsearch插件,提供了列出elasticsearch索引的功能,而不需要任何其他信息。你可以在以下网址找到它:

http://blog.iterativ.ch/2014/04/11/listindices-writing-your-first-elasticsearch-java-plugin/

https://github.com/iterativ/elasticsearch-listindices

curl -XGET 'http://localhost:9200/_cluster/health?水平=指数'

这将输出如下所示

{
  "cluster_name": "XXXXXX:name",
  "status": "green",
  "timed_out": false,
  "number_of_nodes": 3,
  "number_of_data_nodes": 3,
  "active_primary_shards": 199,
  "active_shards": 398,
  "relocating_shards": 0,
  "initializing_shards": 0,
  "unassigned_shards": 0,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks": 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 100,
  "indices": {
    "logstash-2017.06.19": {
      "status": "green",
      "number_of_shards": 3,
      "number_of_replicas": 1,
      "active_primary_shards": 3,
      "active_shards": 6,
      "relocating_shards": 0,
      "initializing_shards": 0,
      "unassigned_shards": 0
    },
    "logstash-2017.06.18": {
      "status": "green",
      "number_of_shards": 3,
      "number_of_replicas": 1,
      "active_primary_shards": 3,
      "active_shards": 6,
      "relocating_shards": 0,
      "initializing_shards": 0,
      "unassigned_shards": 0
    }}

我在一台机器上安装了Kibana和ES。但是我不知道该机器上ES节点的详细信息(在什么路径或端口)。

那么,如何从Kibana(5.6版)进行操作呢?

转到开发工具 请参阅控制台部分,并运行以下查询:

把_cat - indices

我感兴趣的是找到特定ES索引的大小

下面是查看db中索引的另一种方法:

curl -sG somehost-dev.example.com:9200/_status --user "credentials:password" | sed 's/,/\n/g' | grep index | grep -v "size_in" | uniq


{ "index":"tmpdb"}

{ "index":"devapp"}

您还可以使用获取特定的索引

curl -X GET "localhost:9200/<INDEX_NAME>"
e.g.   curl -X GET "localhost:9200/twitter"
You may get output like:
{
  "twitter": {
     "aliases": { 

     },
     "mappings": { 

     },
     "settings": {
     "index": {
        "creation_date": "1540797250479",
        "number_of_shards": "3",
        "number_of_replicas": "2",
        "uuid": "CHYecky8Q-ijsoJbpXP95w",
        "version": {
            "created": "6040299"
        },
       "provided_name": "twitter"
      }
    }
  }
}
