== Indices

The `indices` command provides a cross-section of each index.  This
information *spans nodes*.

[source,shell]
--------------------------------------------------
% curl 'localhost:9200/_cat/indices/twi*?v'
health index    pri rep docs docs/del size/pri size/total
green  twitter    2   0  627        7      2mb        2mb
green  twitter2   2   0  628        0    2.5mb      2.5mb
--------------------------------------------------

We can tell quickly how many shards make up an index, the number of
docs, deleted docs, primary store size, and total store size (all
shards including replicas).

What's my largest index by disk usage not including replicas?

[source,shell]
--------------------------------------------------
% curl 'localhost:9200/_cat/indices?bytes=b' | sort -rnk7
green  twitter      2 0 627 7 2123797 2123797
