Auth

Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.

Important

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

Required authorization

Path parameters

name union string | string[] optional

A comma-separated list of aliases to retrieve. Supports wildcards (*). To retrieve all aliases, omit this parameter or use * or _all.

Leave it out to use /_cat/aliases.

Query parameters

h union oneOf

A comma-separated list of columns names to display. It supports simple wildcards.

Supported values include:

alias (or a): The name of the alias.
index (or i, idx): The name of the index the alias points to.
filter (or f, fi): The filter applied to the alias.
routing.index (or ri, routingIndex): Index routing value for the alias.
routing.search (or rs, routingSearch): Search routing value for the alias.
is_write_index (or w, isWriteIndex): Indicates if the index is the write index for the alias.

Values: alias a index i idx filter f fi routing.index ri routingIndex routing.search rs routingSearch is_write_index w isWriteIndex

s union string | 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.

expand_wildcards union oneOf · default: all

The 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. It 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: all open closed hidden none

local boolean · default: false

If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

format string · default: text

Specifies the format to return the columnar data in, can be set to text, json, cbor, yaml, or smile.

help boolean · default: false

When set to true will output available columns. This option can't be combined with any other query string option.

v boolean · default: false

When set to true will enable verbose output.

bytes enum

Sets the units for columns that contain a byte-size value. Note that byte-size value units work in terms of powers of 1024. For instance 1kb means 1024 bytes, not 1000 bytes. If omitted, byte-size values are rendered with a suffix such as kb, mb, or gb, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, byte-size values are rendered as an integer with no suffix, representing the value of the column in the chosen unit. Values that are not an exact multiple of the chosen unit are rounded down.

Values: b kb mb gb tb pb

time enum

Sets the units for columns that contain a time duration. If omitted, time duration values are rendered with a suffix such as ms, s, m or h, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, time duration values are rendered as an integer with no suffix. Values that are not an exact multiple of the chosen unit are rounded down.

Values: nanos micros ms s m h d
