Elasticsearchのcat indices

Elasticsearchのcat indicesについて記す。

公式ドキュメント cat indices を参考にした。 www.elastic.co

検証環境: Elasticsearch 6.0.0-rc1

cat indicesは各インデックスの詳細情報を示す。cat indicesの情報はノードにまたがる。

Note:
* これに表示されている情報はLucene levelである。文書と削除された文書の数は Lucene APIsからとってきた情報であるため、すべてのhidden documents(ネストされた文書など)も含まれる。 * Elasticsearch levelで文書の実際の数を取得するには、cat countまたはCount APIのどちらかを使用することをすすめる。
