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

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:
