cat aliases

The cat aliases operation lists the mapping of aliases to indices, plus routing and filtering information.

Example

GET _cat/aliases?v

To limit the information to a specific alias, add the alias name after your query:

GET _cat/aliases/<alias>?v

If you want to get information for more than one alias, separate the alias names with commas:

GET _cat/aliases/alias1,alias2,alias3

Path and HTTP methods

GET _cat/aliases/<alias>
GET _cat/aliases

URL parameters

All cat aliases URL parameters are optional.

In addition to the common URL parameters, you can specify the following parameters:

Parameter	Type	Description
local	Boolean	Whether to return information from the local node only instead of from the master node. Default is false.
expand_wildcards	Enum	Expands wildcard expressions to concrete indices. Combine multiple values with commas. Supported values are `all`, `open`, `closed`, `hidden`, and `none`. Default is `open`.

Response

The following response shows that alias1 refers to a movies index and has a configured filter:

alias   | index     | filter  | routing.index | routing.search  | is_write_index
alias1  | movies    |   *     |      -        |       -         |      -
.kibana | .kibana_1 |   -     |      -        |       -         |      -
