Retrieving a List of All Elasticsearch Indices in Magento 2
To view all Elasticsearch indices in Magento 2, use the following command:
curl -X GET "http://localhost:9200/_cat/indices?v"
This command retrieves a list of indices from your Elasticsearch server. If your server isn't running on localhost, replace it with your server's hostname.
The output will display details like health status, index name, document count, and storage size. For example:
If you need to delete all indices, execute:
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open magento_default_catalog_product_20230703_022952 bjHqWsUATpGg1xwnnB5YAg 1 0 0 0 283b 283b
In this output:
- health: Indicates the index's health status. 'Green' means healthy.
- index: The name of the index.
- docs.count: Number of documents in the index.
- store.size: Size of the index on disk.
This information helps monitor and manage your Magento 2 store's search indices effectively.
For a more detailed view, including aliases, use:
curl -X DELETE "http://localhost:9200/*?pretty"
This command lists all indices along with their aliases, providing a comprehensive overview of your Elasticsearch setup.
If you need to delete all indices, execute:
curl -X DELETE "http://localhost:9200/*?pretty"
Use this command with caution, as it removes all indices from your Elasticsearch server.
Regularly checking your Elasticsearch indices ensures your Magento 2 store's search functionality operates smoothly.
