Get index information

GET /_cat/indices

Returns high-level information about indices in a cluster, including backing indices for data streams.

Use this request to get the following information for each index in a cluster:

shard count
document count
deleted document count
primary store size
total store size of all shards, including shard replicas

These metrics are retrieved directly from Lucene, which Elasticsearch uses internally to power indexing and search. As a result, all document counts include hidden nested documents. To get an accurate count of Elasticsearch documents, use the cat count or count APIs.

CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use an index endpoint.

Query parameters

bytes string

The unit used to display byte values.

Values are b, kb, mb, gb, tb, or pb.
expand_wildcards string | array[string]

The type of index that wildcard patterns can match.
health string

The health status used to limit returned indices. By default, the response includes indices of any health status.

Values are green, GREEN, yellow, YELLOW, red, or RED.
include_unloaded_segments boolean

If true, the response includes information from segments that are not loaded into memory.
pri boolean

If true, the response only includes information from primary shards.
time string

The unit used to display time values.

Values are nanos, micros, ms, s, m, h, or d.
