Information about existing OpenSearch clusters

Written by
Updated at January 30, 2026

You can get detailed information about each Managed Service for OpenSearch cluster you created.

Getting a list of clusters in a folder

  1. In the management console, navigate to the folder page.
  2. Navigate to the Managed Service for OpenSearch service.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To get a list of OpenSearch clusters in the default folder, run this command:

yc managed-opensearch cluster list

+----------------------+------+-----------------------------+--------+---------+
|          ID          | NAME |         CREATED AT          | HEALTH | STATUS  |
+----------------------+------+-----------------------------+--------+---------+

+----------------------+------+-----------------------------+--------+---------+

  1. Get an IAM token for API authentication and put it in an environment variable:

    export IAM_TOKEN="<IAM_token>"

  2. Call the Cluster.List method, e.g., via the following cURL request:

    curl \
    --request GET \
    --header "Authorization: Bearer $IAM_TOKEN" \
    --url 'https://mdb.api.cloud.yandex.net/managed-opensearch/v1/clusters' \
    --url-query folderId=<folder_ID>

    You can get the folder ID with the list of folders in the cloud.

  3. View the server response to make sure your request was successful.

  1. Get an IAM token for API authentication and put it in an environment variable:

    export IAM_TOKEN="<IAM_token>"

  2. Clone the cloudapi repository:

    Below, we assume that the repository contents reside in the ~/cloudapi/ directory.

  3. Call the ClusterService.List method, e.g., via the following gRPCurl request:

    grpcurl \
    -format json \
    -import-path ~/cloudapi/ \

Viewing operations with clusters

All actions with Managed Service for OpenSearch clusters are logged as a list of operations. Each operation gets its own unique ID.

Getting a list of operations

To get a list of operations for a cluster:

  1. In the management console, open the folder containing your cluster.

  2. Navigate to the Managed Service for OpenSearch service.

  3. In the left-hand panel, select Clusters.

  4. Select the cluster you need.

  5. Navigate to the Operations panel for the cluster you selected.

    You will see the list of operations with this cluster.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To get a list of operations for a Managed Service for OpenSearch cluster, run this command:

yc managed-opensearch cluster list-operations <cluster_name_or_ID>

Result:

+----------------------+---------------------+----------------------+---------------------+--------+---------------------------+
|          ID          |     CREATED AT      |      CREATED BY      |     MODIFIED AT     | STATUS |        DESCRIPTION        |

+----------------------+---------------------+----------------------+---------------------+--------+---------------------------+

You can get the cluster ID with the list of clusters in the folder.

By default, information about operations is output as text. To get more detailed information, specify the yaml or json output data format using --format:

yc managed-opensearch cluster list-operations c9qk2926qqu9******** --format yaml

Getting operation details

  1. Navigate to the list of operations for your cluster.
  2. Click the ID of the operation you need.

Note

Operations where details are available have the icon next to their ID.

Operation details include a hierarchical list of the operation steps. The first-level items are actions with the cluster, and the second-level ones are actions with hosts. The list may vary for different operations:

  • If a step is running or has completed, its start date and time are displayed.
  • If a step has not yet started, it has the In queue status.

The list displays the following actions:

  • Preparing metadata: Preparing information and data for the operation.
  • Preparing backup storage: Preparing storage for backups.
  • Creating cluster: Creating a cluster.
  • Installing software: Installing software (e.g., creating a database or installing auxiliary plugin packages).
  • Initializing database: Initializing a database.
  • Infrastructure integration: Creating connections between new objects and the Yandex Cloud infrastructure (e.g., DNS propagation, issuing certificates, adding hosts to the monitoring system).
  • Updating host groups: Updating a host group.
  • Updating hosts: Updating hosts.
  • Completing: Completing the operation.

Actions with hosts:

  • Reserving resources: Allocating resources for a host.
  • Creating host: Creating a host.
  • Launching host: Starting a host.
  • Preparing host: Preparing a host.
  • Updating database software: Updating software.
  • Updating database services: Updating database services.
  • Creating DNS records: Creating a DNS record.
  • Restarting database: Restarting a database.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To get detailed information about an operation, run this command:

yc operation get <operation_ID>

You can get the operation ID with the list of operations for the cluster.

Here is an example of an output for the completed cluster creation operation:
