CAT aliases
Introduced 1.0
The CAT aliases operation lists the mapping of aliases to indexes, plus routing and filtering information.
Path and HTTP methods
GET _cat/aliases/<alias>
GET _cat/aliases
Query parameters
| Parameter | Type | Description |
|---|---|---|
| local | Boolean | Whether to return information from the local node only instead of from the cluster manager node. Default is false. |
| expand_wildcards | Enum | Expands wildcard expressions to concrete indexes. Combine multiple values with commas. Supported values are all, open, closed, hidden, and none. Default is open. |
Example requests
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
Example 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 | * | - | - | -
.opensearch-dashboards | .opensearch-dashboards_1 | - | - | - | -
