Viewing Elasticsearch Cluster Information
On the Elasticsearch/OpenSearch cluster list and cluster information page, you can check the cluster status, version, and node information.
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.
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.
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_xxxx), 7.10.2 is the cluster version and 7.10.2_x.x.x_xxxx is the image version.
|
Created |
Cluster creation time. |
Enterprise Project |
Enterprise project that a cluster belongs to. |
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. |
Billing Mode |
Billing mode of a cluster. It can be Pay-per-use or Yearly/Monthly. |
Operation |

Table 2 Parameters for configuring basic information Type
Parameter
Description
Cluster Information
Name
Cluster name. The name can be customized.
You can click
on the right to change the cluster name.
Initial Name
Name of the cluster when it was created for the first time, which is unique and cannot be modified.
ID
Unique ID of a cluster, which is automatically generated by the system.
Each cluster in the same region has a unique ID.
Version
Cluster version information.
For example, if the version is 7.10.2(7.10.2_x.x.x_xxxx), 7.10.2 is the cluster version and 7.10.2_x.x.x_xxxx is the image version.
NOTE:
- For a cluster created a long time ago, its image version may not be available because it may not be 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.
Cluster Status
Current status of a cluster
Task Status
Current task status of a cluster. If no task is in progress, -- is displayed.
Created
Time when a cluster was created
Cluster Storage Capacity (GB)
Storage capacity of a cluster
Used Cluster Storage (GB)
Used storage capacity of a cluster
Configuration
Region
Region where a cluster is located
AZ
AZ where a cluster is located
VPC
VPC to which the cluster belongs
Subnet
Subnet to which the cluster belongs
Security Group
Security group to which a cluster belongs.
To change the security group of a cluster, click Change Security Group on the right.
NOTICE:Before changing the security group, ensure that the port 9200 required for service access has been enabled. Incorrect security group configuration may cause service access failures. Exercise caution when performing this operation.
Security Mode
Security mode of a cluster.
- Enabled: The current cluster is a security cluster.
- Disabled: The current cluster is a non-security cluster.
For details about how to change the security mode of a cluster, see Changing the Security Mode of an Elasticsearch Cluster.
Reset Password
This parameter is displayed only for security clusters.
Click Reset to change the password of the administrator account admin of the security cluster.
NOTE:
Requirements for administrator passwords:
- The password can contain 8 to 32 characters.
- The password must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters. The following special characters are allowed: ~!@#$%^&*()-_=+\|[{}];:,<.>/?
- Do not use the administrator name, or the administrator name spelled backwards.
- You are advised to change the password periodically.
Enterprise Project
Enterprise project to which a cluster belongs.
You can click the project name to view the basic information about the enterprise project.
Public IP Address
Public network access information, which is displayed only for clusters in security mode.
- For a security cluster with public network access enabled, the configured public network address is displayed. You can use this address to access the security cluster from the public network.
- For a security cluster with public network access disabled, -- is displayed.
When using a public IP address to access a cluster, you are advised to enable access control and configure an access whitelist to improve cluster security. For details about how to configure the public network access, see Configuring Public Network Access for an Elasticsearch Cluster.
Access Control
Whether to set access control for a cluster. This parameter is displayed only for clusters with public network access enabled.
- Enabled: Only IP addresses in the whitelist can access the cluster through the public network.
- Disabled: Any IP address can access the cluster through the public network.
Click Set to configure the access control and the whitelist.
Bandwidth
The bandwidth for public network access. This parameter is displayed only for clusters with public network access enabled.
Click Edit to change the bandwidth size.
HTTPS Access
Whether to enable the HTTPS access protocol for a cluster.
- If HTTPS access is disabled, the cluster uses the HTTP protocol.
- If it is enabled, the HTTPS protocol is used for cluster access. Only security-mode clusters can enable this function. If HTTPS Access is enabled, you can click Download Certificate to obtain the CER security certificate for accessing the security cluster. Currently, the security certificate cannot be used in the public network environment.
For details about how to change the access mode of a cluster in security mode, see Switching the Protocol of Security Clusters.
Private IPv4 Address
Private IP address and port number of a cluster, which can be used to access the cluster. If the cluster has only one node, the IP address and port number of only one node are displayed, for example, 10.62.179.32:9200. If the cluster has multiple nodes, the IP addresses and port numbers of all nodes are displayed, for example, 10.62.179.32:9200,10.62.179.33:9200.
