Manage Indices via Kibanaedit
The Kibana UI for managing indices allows you to view indices, index settings, mappings, document counts, used storage per index, and much more. You can also perform management operations, like deleting indices directly via the Kibana UI. Finally, the UI supports applying bulk operations on several indices at once.
