Viewing Elasticsearch Cluster Information

On the CSS management console, you can check an Elasticsearch cluster's status, version, nodes, configurations and settings, and resource allocation on the cluster list and the cluster information page.

Introduction to Cluster Lists

A cluster list displays all clusters of the same type under the current account. If there are a large number of clusters, the cluster list will consist of multiple pages, showing clusters of all states.

Clusters are listed in chronological order by default in the cluster list, with the most recent clusters displayed at the top.

You can click Export to download the full cluster list.

Table 1 Cluster list parameters

Parameter

Description

Name/ID

Name and ID of a cluster. You can click a cluster name to switch to the Cluster Information page. The cluster ID is automatically generated by the system and uniquely identifies a cluster.

Cluster Status

Current status of a cluster.

  • Available: The cluster is running properly.
  • Creating: The cluster is being created.
  • Processing: The cluster is being restarted, scaled out, backed up, or restored.
  • Abnormal: The cluster failed to be created or is unavailable.
WARNING:

If a cluster is unavailable, you can delete the cluster or use a snapshot created when the cluster was available to restore its data to another cluster. However, you cannot scale out this cluster, access it through Kibana, create snapshots for it, or use an existing snapshot to restore its data to itself. Do not try to import data into a cluster that is unavailable, as the data may get lost. For such a cluster, you can check its monitoring data or restart it to try to fix the problem. If the fault persists, contact technical support.

Task Status

Status of a task, such as cluster restart, scale-out, or scale-in.

Version

Cluster version and image version.

For example, if the version is 7.10.2(7.10.2_x.x.x_x.x.x), 7.10.2 is the cluster version and 7.10.2_x.x.x_x.x.x enclosed in parentheses is the image version.
CAUTION:
  • For a cluster created a long time ago, its image version may not be available because it is likely not recorded in the database.
  • If EOS is displayed below the version number, the current version has reached EOS and hence poses certain service availability risks. You are advised to upgrade the cluster version as soon as possible. For details, see Upgrading the Version of an Elasticsearch Cluster.

Created

Cluster creation time.

Enterprise Project

Enterprise project that a cluster belongs to.

Security Mode

Whether the security mode is enabled for the cluster. Only authorized users can access a security-mode cluster.

Private Network Address

Private network address and port number of a cluster. You can use it to access the cluster. If the cluster has multiple nodes, the private network addresses and port numbers of all nodes are displayed.

VPC Endpoint Address

IP address or private domain name of the VPC endpoint associated with the cluster.

Billing Mode

Billing mode of a cluster. It can be Pay-per-use or Yearly/Monthly.

Associated Cluster

Name and ID of a cluster associated with the current cluster.

  • The associated cluster is the parent cluster of the current cluster. For example, when KooSearch uses an Elasticsearch cluster as a vector database, the KooSearch service is the associated cluster of this Elasticsearch cluster.
  • If any of the following operations is performed on the associated cluster, it will also be performed on the current cluster in a synchronized manner: deletion, unsubscription, renewal, and change of billing mode.
  • The following operations cannot be performed alone on an Elasticsearch cluster that has an associated cluster: deletion, unsubscription, renewal, and change of billing mode or security mode.
  • You can click the name of an associated cluster to go to its details page and check its configuration and status.

Operation

Operations that can be performed on a cluster, such as checking metrics, restart, and deletion. If an operation is unavailable, the menu button is grayed out.

Viewing Basic Cluster Information

On the Cluster Information page, you can check the information of a cluster, including the private network address, public IP address, version, and nodes.

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > Elasticsearch to show the Elasticsearch cluster list.
  3. In the cluster list, click a cluster name to go to the Cluster Information page and view basic information about the cluster.

Checking the Dependent Services of a Cluster

A cluster exists as a parent service for services that it depends on. For example, in the context of AI search, an Elasticsearch cluster may depend on a dedicated AI search model. In this case, the dedicated search model is a dependent service of this Elasticsearch cluster.

If any of the following operations is performed on an Elasticsearch cluster, it will also be performed on its dependent services in a synchronized manner: deletion, unsubscription, renewal, and change of billing mode.

You can view and manage the dependent services of a cluster.

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > Elasticsearch to show the Elasticsearch cluster list.
  3. In the cluster list on the displayed page, click the target cluster name to switch to the Cluster Information page.
  4. In the navigation pane on the left, choose Dependent Services.

    You can check the configuration and status of each dependent service. You can also click Details in the Operation column to go to the details page and manage the dependent service.

    For a dependent service of an Elasticsearch cluster, the following operations are disallowed: deletion, unsubscription, renewal, and change of billing mode.
