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
|
2016-04-07 05:15:32 -04:00
|
|
|
docs at the Lucene level, including hidden docs (e.g., from nested types),
|
|
|
|
|
deleted docs, primary store size, and total store size (all shards including replicas).
|
|
|
|
|
All these exposed metrics come directly from Lucene APIs.

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.
