How to list indexes in OpenSearch with Logit.io?

Listing indexes in your OpenSearch cluster is a basic operation that allows you to see all available indexes and their status. Follow this guide to learn how to list all indexes in your Logit.io hosted OpenSearch service.

Step 1: Access the OpenSearch Dashboard

Once logged in to Logit.io, navigate to the OpenSearch Dashboards by clicking Launch Logs.

Step 2: Open the Dev Tools

Logit.io's OpenSearch Dashboards provide a Dev Tools feature, which is an integrated console for directly executing OpenSearch queries and commands.

In the OpenSearch Dashboards, locate and click on "Dev Tools" on the left-hand navigation bar.

You will be presented with a console where you can input and execute commands.

Step 3: List All Indexes

To list all indexes in your OpenSearch cluster, you can use the _cat/indices API, which provides a human-readable overview of index properties.

In the Dev Tools console, enter the following command to list all indexes:

GET /_cat/indices?v

Press Enter to execute the command.

The v parameter in the command asks for verbose output, meaning it will include headers in the output.

This command will display a list of all indexes along with essential details such as index names, the number of documents, and the size of the disk.

Understanding the Output

The output from the _cat/indices command provides several pieces of information for each index, including:

• health: Indicates the health status of the index (green, yellow, or red).
• status: Shows whether the index is open or closed.
• index: The name of the index.
• uuid: The unique identifier of the index.
• pri: The number of primary shards.
• rep: The number of replica shards.
• docs.count: The number of documents in the index.
• docs.deleted: The number of deleted documents in the index.
• store.size: The total size taken by the index on disk.
• pri.store.size: The size taken by primary shards on disk.
