Returns statistics for one or more indices. For data streams, the API retrieves
|
|
statistics for the stream's backing indices.

|
|
==== {api-description-title}
|
|
|
|
Use the index stats API to get high-level aggregation and statistics for one or
|
|
more data streams and indices.
|
|
|
|
By default,
|
|
the returned statistics are index-level
|
|
with `primaries` and `total` aggregations.
|
|
`primaries` are the values for only the primary shards.
|
|
`total` are the accumulated values for both primary and replica shards.
|
|
|
|
To get shard-level statistics,
|
|
set the `level` parameter to `shards`.
|
|
|
|
[NOTE]
|
|
====
|
|
When moving to another node,
|
|
the shard-level statistics for a shard are cleared.
|
|
Although the shard
|
|
is no longer part of the node,
|
|
that node retains any node-level statistics
|
|
to which the shard contributed.
