== Indices

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

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).

=== Primaries
|
|
|
|
|
|
|
|
|
|
The index stats by default will show them for all of an index's
|
|
|
|
|
shards, including replicas. A `pri` flag can be supplied to enable
|
|
|
|
|
the view of relevant stats in the context of only the primaries.
