Elasticsearch cat shards size pri. Every index is divided into one or more shards to help distribute data and workload across nodes in a cluster. We are using index names to reach the documents stored in shard (s) or replica (s) in primary store size total store size of all shards, including shard replicas These metrics are retrieved directly from Lucene, which Elasticsearch uses internally to power indexing and search. For the size of our cluster, /_cat/indices [1] returns close to a thousand lines. This article delves into what shards and cat APIs are only intended for human consumption using the command line or Kibana console.
