Get index information

GET /_cat/indices
Api key auth Basic auth Bearer auth

Get high-level information about indices in a cluster, including backing indices for data streams.

Use this request to get the following information for each index in a cluster:

  • shard count
  • document count
  • deleted document count
  • 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. 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.

CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use an index endpoint.

Query parameters

  • bytes string

    The unit used to display byte values.

    Values are b, kb, mb, gb, tb, or pb.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match.

  • health string

    The health status used to limit returned indices. By default, the response includes indices of any health status.

    Values are green, GREEN, yellow, YELLOW, red, or RED.

  • include_unloaded_segments boolean

    If true, the response includes information from segments that are not loaded into memory.

  • pri boolean

    If true, the response only includes information from primary shards.

  • time string

    The unit used to display time values.

    Values are nanos, micros, ms, s, m, h, or d.

  • master_timeout string

    Period to wait for a connection to the master node.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

Get the cluster state Added in 1.3.0

GET /_cluster/state/{metric}
Api key auth Basic auth Bearer auth

Get comprehensive information about the state of the cluster.

The cluster state is an internal data structure which keeps track of a variety of information needed by every node, including the identity and attributes of the other nodes in the cluster; cluster-wide settings; index metadata, including the mapping and settings for each index; the location and status of every shard copy in the cluster.

The elected master node ensures that every node in the cluster has a copy of the same cluster state. This API lets you retrieve a representation of this internal state for debugging or diagnostic purposes. You may need to consult the Elasticsearch source code to determine the precise meaning of the response.

By default the API will route requests to the elected master node since this node is the authoritative source of cluster states. You can also retrieve the cluster state held on the node handling the API request by adding the ?local=true query parameter.

Elasticsearch may need to expend significant effort to compute a response to this API in larger clusters, and the response may comprise a very large quantity of data. If you use this API repeatedly, your cluster may become unstable.

WARNING: The response is a representation of an internal data structure. Its format is not subject to the same compatibility guarantees as other more stable APIs and may change from version to version. Do not query this API using external monitoring tools. Instead, obtain the information you require using other more stable cluster APIs.

  • flat_settings boolean

    Return settings in flat format (default: false)

  • ignore_unavailable boolean

    Whether specified concrete indices should be ignored when unavailable (missing or closed)

  • local boolean

    Return local information, do not retrieve the state from master node (default: false)

  • master_timeout string

    Specify timeout for connection to master

  • wait_for_metadata_version number

    Wait for the metadata version to be equal or greater than the specified metadata version

Create or update a component template Added in 7.8.0

PUT /_component_template/{name}
Api key auth Basic auth Bearer auth

Component templates are building blocks for constructing index templates that specify index mappings, settings, and aliases.

An index template can be composed of multiple component templates. To use a component template, specify it in an index template’s composed_of list. Component templates are only applied to new data streams and indices as part of a matching index template.

Settings and mappings specified directly in the index template or the create index request override any settings or mappings specified in a component template.

Component templates are only used during index creation. For data streams, this includes data stream creation and the creation of a stream’s backing indices. Changes to component templates do not affect existing indices, including a stream’s backing indices.

You can use C-style /* *\/ block comments in component templates. You can include comments anywhere in the request body except before the opening curly bracket.

Applying component templates

You cannot directly apply a component template to a data stream or index. To be applied, a component template must be included in an index template's composed_of list.

Path parameters

  • name string Required

    Name of the component template to create. Elasticsearch includes the following built-in component templates: logs-mappings; logs-settings; metrics-mappings; metrics-settings;synthetics-mapping; synthetics-settings. Elastic Agent uses these templates to configure backing indices for its data streams. If you use Elastic Agent and want to overwrite one of these templates, set the version for your replacement template higher than the current version. If you don’t use Elastic Agent and want to disable all built-in component and index templates, set stack.templates.enabled to false using the cluster update settings API.

Query parameters

  • create boolean

    If true, this request cannot replace or update existing component templates.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

        • origination_date number

          If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

        • parse_origination_date boolean

          Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

          • limit number | string

            The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

            One of:
            number-1 number string-2 string

          • ignore_dynamic_beyond_limit boolean | string

            This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

          Hide depth attribute Show depth attribute object
          • limit number

            The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

        • nested_fields object
          Hide nested_fields attribute Show nested_fields attribute object
          • limit number

            The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

        • nested_objects object
          Hide nested_objects attribute Show nested_objects attribute object
          • limit number

            The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

        • field_name_length object
          Hide field_name_length attribute Show field_name_length attribute object
          • limit number

            Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

        • dimension_fields object
          Hide dimension_fields attribute Show dimension_fields attribute object

          If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

        • parse_origination_date boolean

          Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

            The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

          • ignore_dynamic_beyond_limit boolean | string

            This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

            The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

        • nested_fields object
          Hide nested_fields attribute Show nested_fields attribute object
          • limit number

            The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

        • nested_objects object
          Hide nested_objects attribute Show nested_objects attribute object
          • limit number

            The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

        • field_name_length object
          Hide field_name_length attribute Show field_name_length attribute object
          • limit number

            Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

Get index settings

GET /_settings
Api key auth Basic auth Bearer auth

Get setting information for one or more indices. For data streams, it returns setting information for the stream's backing indices.

Query parameters

  • allow_no_indices boolean

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[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.

  • flat_settings boolean

    If true, returns settings in flat format.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • include_defaults boolean

    If true, return all default settings in the response.

  • local boolean

    If true, the request retrieves information from the local node only. If false, information is retrieved from the master node.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

            If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

          • parse_origination_date boolean

            Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions.

            • ignore_dynamic_beyond_limit boolean | string

              This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

              The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

          • nested_fields object
            Hide nested_fields attribute Show nested_fields attribute object
            • limit number

              The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

          • nested_objects object
            Hide nested_objects attribute Show nested_objects attribute object
            • limit number

          • field_name_length object
            Hide field_name_length attribute Show field_name_length attribute object
            • limit number

              Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

          • origination_date number

            If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

          • parse_origination_date boolean

            Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

            • limit number | string

              The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

              number-1 number string-2 string

            • ignore_dynamic_beyond_limit boolean | string

              This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

          • depth object
            Hide depth attribute Show depth attribute object
            • limit number

              The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

          • nested_fields object
            Hide nested_fields attribute Show nested_fields attribute object
            • limit number

              The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

          • nested_objects object
            Hide nested_objects attribute Show nested_objects attribute object
            • limit number

              The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

          • field_name_length object
            Hide field_name_length attribute Show field_name_length attribute object
            • limit number

              Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).
