Path parameters

• index string | array[string] Required

  Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

• name string | array[string] Required

  Comma-separated list or wildcard expression of settings to retrieve.

Query parameters

• allow_no_indices boolean

  A setting that does two separate checks on the index expression. If false, the request returns an error (1) if any wildcard expression (including _all and *) resolves to zero matching indices or (2) if the complete set of resolved indices, aliases or data streams is empty after all expressions are evaluated. If true, index expressions that resolve to no indices are allowed and the request returns an empty result.

• 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.

  Supported values include:

  • all: Match any data stream or index, including hidden ones.
  • open: Match open, non-hidden indices. Also matches any non-hidden data stream.
  • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
  • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
  • none: Wildcard expressions are not accepted.

  Values are all, open, closed, hidden, or none.

• flat_settings boolean

  If true, returns settings in flat format.

• ignore_unavailable boolean

  If false, the request returns an error if it targets a concrete (non-wildcarded) index, alias, or data stream that is missing, closed, or otherwise unavailable. If true, unavailable concrete targets are silently ignored.

• include_defaults boolean

  If true, return all default settings in the response.

• local boolean Deprecated

  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.

        • filter object

          Query used to limit documents the alias can access.

        • index_routing string

          Value used to route indexing operations to a specific shard. If specified, this overwrites the routing value for indexing operations.

        • is_hidden boolean

          If true, the alias is hidden. All indices for the alias must have the same is_hidden value.

          Default value is false.

        • is_write_index boolean

          If true, the index is the write index for the alias.

          Default value is false.

        • routing string

          Value used to route indexing and search operations to a specific shard.

        • search_routing string

          Value used to route search operations to a specific shard. If specified, this overwrites the routing value for search operations.

      Index settings
    • data_stream string
    • lifecycle object Generally available

      Data stream lifecycle applicable if this is a data stream.

      Hide lifecycle attributes Show lifecycle attributes object

      • data_retention string

        If defined, every document added to this data stream will be stored at least for this time frame. Any time after this duration the document could be deleted. When empty, every document in this data stream will be stored indefinitely.

      • downsampling array[object]

        The list of downsampling rounds to execute as part of this downsampling configuration
      • downsampling_method string

        The method used to downsample the data. There are two options aggregate and last_value. It requires downsampling to be defined. Defaults to aggregate.

        Values are aggregate or last_value.

      • enabled boolean

        If defined, it turns data stream lifecycle on/off (true/false) for this data stream. A data stream lifecycle that's disabled (enabled: false) will have no effect on the data stream.

        Default value is true.

      • frozen_after string

        Only available with feature flag dlm_searchable_snapshots.
