The web-based Kibana user interface must also be installed on the local machine. The repositories should always be update, using the following command, before any packages are installed on Ubuntu:.

Elasticsearch get index names

They are not intended for use by applications. For application consumption, use the get index API. Returns high-level information about indices in a cluster, including backing indices for data streams. These metrics are retrieved directly from Lucene , which Elasticsearch uses internally to power indexing and search. As a result, all document counts include hidden nested documents. To get an accurate count of Elasticsearch documents, use the cat count or count APIs. Optional, string Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are:. Request edit. Prerequisites edit. If the Elasticsearch security features are enabled, you must have the monitor or manage cluster privilege to use this API.

Skip this section if Elasticsearch is already installed.

In Elasticsearch, an index plural: indices contains a schema and can have one or more shards and replicas. An Elasticsearch index is divided into shards and each shard is an instance of a Lucene index. Indices are used to store the documents in dedicated data structures corresponding to the data type of fields. For example, text fields are stored inside an inverted index whereas numeric and geo fields are stored inside BKD trees. The following example is based on Elasticsearch version 5.
