List all indexes on ElasticSearch server?

Question

I would like to list all indexes present on an ElasticSearch server. I tried this:

curl -XGET localhost:9200/

but it just gives me this:

Answer 1

You can also get specific index using

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"
      }
    }
  }
}

Answer 2

send requtest and get response with kibana,kibana is can autocomplete elastic query builder and have more tools

look at the kibana

 GET /_cat/indices

kibana dev tools

http://localhost:5601/app/kibana#/dev_tools/console

Answer 3

curl -XGET 'http://localhost:9200/_cluster/health?level=indices'

This will output like below

{
  "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
    }}

Answer 4

I would also recommend doing /_cat/indices which gives a nice human readable list of your indexes.

Answer 5

The _stats command provides ways to customize the results by specifying the metrics wished. To get the indices the query is as follows:

GET /_stats/indices

The general format of the _stats query is:

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

Where the metrics are:

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

As an exercice to myself, I've written a small elasticsearch plugin providing the functionality to list elasticsearch indices without any other information. You can find it at the following url:

Answer 6

_stats/indices gives the result with indices.

$ curl -XGET "localhost:9200/_stats/indices?pretty=true"
{
  "_shards" : {
    "total" : 10,
    "successful" : 5,
    "failed" : 0
  },
  "_all" : {
    "primaries" : { },
    "total" : { }
  },
  "indices" : {
    "visitors" : {
      "primaries" : { },
      "total" : { }
    }
  }
}
