For a concise list of all indices in your cluster, call 

<pre><code>curl http://localhost:9200/_aliases
</code></pre>

this will give you a list of indices and their aliases.

If you want it pretty-printed, add <code>pretty=true</code>:

<pre><code>curl http://localhost:9200/_aliases?pretty=true
</code></pre>

The result will look something like this, if your indices are called <code>old_deuteronomy</code> and <code>mungojerrie</code>:

<pre><code>{
 "old_deuteronomy" : {
 "aliases" : { }
 },
 "mungojerrie" : {
 "aliases" : {

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

<pre><code>GET /_stats/indices
</code></pre>

The general format of the <code>_stats</code> query is:

<pre><code>/_stats
/_stats/{metric}
/_stats/{metric}/{indexMetric}
/{index}/_stats
/{index}/_stats/{metric}
</code></pre>

Where the metrics are:

<pre><code>indices, docs, store, indexing, search, get, merge, 
refresh, flush, warmer, filter_cache, id_cache, 
percolate, segments, fielddata, completion
</code></pre>

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:

blocks|key|287255|text|获取仅包含索引的列表的最简单方法是使用上面的答案，并带有'h=index‘参数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|287256|curl+-XGET+"localhost:9200/_cat/indices?h=index"|code-block|syntax|javascript|287257|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The simplest way to get a list of only indexes is to use the answer above, with the 'h=index' parameter: 

<pre><code>curl -XGET "localhost:9200/_cat/indices?h=index"

I use the <code>_stats/indexes</code> endpoint to get a json blob of data and then filter with <a href="https://stedolan.github.io/jq/" rel="nofollow">jq</a>.

<pre><code>curl 'localhost:9200/_stats/indexes' | jq '.indices | keys | .[]'

"admin"
"blazeds"
"cgi-bin"
"contacts_v1"
"flex2gateway"
"formmail"
"formmail.pl"
"gw"
...
</code></pre>

If you don't want quotes, add a <code>-r</code> flag to jq.

Yes, the endpoint is <code>indexes</code> and the data key is <code>indices</code>, so they couldn't make up their minds either :)

I needed this to clean up these garbage indices created by an internal security scan (nessus).

PS. I highly recommend getting familiar with <a href="https://stedolan.github.io/jq/" rel="nofollow">jq</a> if you're going to interact with ES from the command line.

If you're working in scala, a way to do this and use <code>Future</code>'s is to create a RequestExecutor, then use the <a href="http://javadoc.kyubu.de/elasticsearch/v1.5.2/org/elasticsearch/action/admin/indices/stats/IndicesStatsRequestBuilder.html" rel="nofollow noreferrer">IndicesStatsRequestBuilder</a> and the administrative client to submit your request. 

<pre><code>import org.elasticsearch.action.{ ActionRequestBuilder, ActionListener, ActionResponse }
import scala.concurrent.{ Future, Promise, blocking }

/** Convenice wrapper for creating RequestExecutors */
object RequestExecutor {
 def apply[T &lt;: ActionResponse](): RequestExecutor[T] = {
 new RequestExecutor[T]
 }
}

/** Wrapper to convert an ActionResponse into a scala Future
 *
 * @see http://chris-zen.github.io/software/2015/05/10/elasticsearch-with-scala-and-akka.html
 */
class RequestExecutor[T &lt;: ActionResponse] extends ActionListener[T] {
 private val promise = Promise[T]()

 def onResponse(response: T) {
 promise.success(response)
 }

 def onFailure(e: Throwable) {
 promise.failure(e)
 }

 def execute[RB &lt;: ActionRequestBuilder[_, T, _, _]](request: RB): Future[T] = {
 blocking {
 request.execute(this)
 promise.future
 }
 }
}
</code></pre>

The executor is lifted from <a href="http://chris-zen.github.io/software/2015/05/10/elasticsearch-with-scala-and-akka.html" rel="nofollow noreferrer">this blog post</a> which is definitely a good read if you're trying to query ES programmatically and not through curl. One you have this you can create a list of all indexes pretty easily like so: 

<pre><code>def totalCountsByIndexName(): Future[List[(String, Long)]] = {
 import scala.collection.JavaConverters._
 val statsRequestBuider = new IndicesStatsRequestBuilder(client.admin().indices())
 val futureStatResponse = RequestExecutor[IndicesStatsResponse].execute(statsRequestBuider)
 futureStatResponse.map { indicesStatsResponse =&gt;
 indicesStatsResponse.getIndices().asScala.map {
 case (k, indexStats) =&gt; {
 val indexName = indexStats.getIndex()
 val totalCount = indexStats.getTotal().getDocs().getCount()
 (indexName, totalCount)
 }
 }.toList
 }
}
</code></pre>

<code>client</code> is an instance of <a href="http://javadoc.kyubu.de/elasticsearch/v1.5.2/org/elasticsearch/client/Client.html" rel="nofollow noreferrer">Client</a> which can be a node or a transport client, whichever suits your needs. You'll also need to have an implicit <code>ExecutionContext</code> in scope for this request. If you try to compile this code without it then you'll get a warning from the scala compiler on how to get that if you don't have one imported already. 

I needed the document count, but if you really only need the names of the indices you can pull them from the keys of the map instead of from the <code>IndexStats</code>:

<pre><code>indicesStatsResponse.getIndices().keySet()
</code></pre>

This question shows up when you're searching for how to do this even if you're trying to do this programmatically, so I hope this helps anyone looking to do this in scala/java. Otherwise, curl users can just do as the top answer says and use

<pre><code>curl http://localhost:9200/_aliases
</code></pre>

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

<pre><code>curl -XGET localhost:9200/
</code></pre>

but it just gives me this:

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

I want a list of all indexes..

List all indexes on ElasticSearch server?

我想列出ElasticSearch服务器上存在的所有索引。我试过这个：curl -XGET localhost:9200/但它只给了我这个：{  "ok" : true,  "status" : 200,  "name" : "El Aguila",  "version" : {    "number" : "0.19.3",    "snapshot_build" : false  },  "t
