On the CSS management console, you can check an Elasticsearch cluster's status, version, nodes, configurations and settings, and resource allocation on both the cluster list and the cluster overview page.
Introduction to the Cluster List
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. The cluster ID is automatically generated by the system and uniquely identifies a cluster. |
Cluster Status | Current status of a cluster.
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. |
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. |
Security Mode | Whether the security mode is enabled for the cluster. Only authorized users can access a security-mode cluster. |
Enterprise Project | Enterprise project that a cluster belongs to. |
Tags | Displays cluster tags. You can click Edit Tag to add, delete, or modify cluster tags. |
Cluster Description | Provides supplementary information about the cluster. |
Created | Cluster creation time. |
Billing Mode | Billing mode of a cluster. |
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. |

Table 2 Basic cluster information Parameter
Description
Cluster ID
Unique ID of a cluster, which is automatically generated by the system.
Each cluster ID is unique within the same region.
Cluster Name
Cluster name.
You can click
to change it. Initial Cluster Name cannot be changed.Initial Cluster Name
This name is unique and cannot be changed. It is only used in the cluster configuration file in YAML.
Cluster Version
Cluster 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 Cluster Version.

Table 4 Network information Parameter
Description
VPC
The VPC to which a cluster belongs.
Current Subnet
The subnet to which a cluster belongs.
If the current subnet cannot meet your service requirements, click Switch Subnet. In the displayed dialog box, select another subnet. If no existing subnets meet your requirements, click Create Subnet to create a new subnet.
CAUTION:- After switching the subnet, the new subnet is used for adding nodes, including scaling, adding dedicated master/client nodes, and enabling VPC Endpoint. IP addresses will be allocated to newly added nodes from the new subnet.
- A cluster can be associated with a maximum of two subnets.
- Subnet switching does not affect the network settings of existing nodes.
Used Subnet
Subnet once used by the cluster.
Security Group
Security group to which a cluster belongs.
To modify the security group of a cluster, click Change Security Group on the right.
WARNING:The selected security group must allow port 9200 in the inbound direction. Otherwise, the cluster may be inaccessible to external services. Furthermore, to enable Kibana private network access, port 5601 must also be allowed.
Security Mode
Security mode of a cluster.
- Enabled: The security mode is enabled for the current cluster.
- Disabled: The security mode is disabled for the current cluster.
You can click
to change the cluster's security mode. For details, see Changing the Security Mode.Reset Password
Change the admin password for a security-mode cluster.
Click Reset to change the password. Requirements for admin 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, as the password.
- Change the password periodically.
This parameter is displayed only when Security Mode is Enabled.
HTTPS Access
Whether to enable HTTPS for a cluster.
- Disabled: The cluster uses HTTP. For a cluster with the security mode disabled, HTTPS is disabled by default.
- Enabled: The cluster uses HTTPS. Only security-mode clusters support HTTPS. If HTTPS Access is enabled, you can click Download Certificate to obtain the certificate used for access control. Currently, the security certificate cannot be used in a public network environment.
For details about how to switch the network protocol for a security-mode cluster, see Switching between HTTP and HTTPS in Security Mode.
Public Network Access
Public network access information of the cluster.
- For a security-mode cluster with public network access enabled, the configured public IP address is displayed.
- For a security-mode cluster with public network access disabled, -- is displayed.
When public network access is enabled for a cluster, you are advised to use a whitelist for access control.
This parameter is displayed only when Security Mode is Enabled.
Bandwidth
Public network bandwidth of the cluster.
Click Edit to change the bandwidth size.
This parameter is displayed only when the security mode and public network access are both enabled for the cluster.
Public Network Access Control
You can configure public network access control for a security-mode cluster by IP addresses or IP address ranges.
Click Modify to modify the access control whitelist.
- If a whitelist is configured, only IP addresses that are on this whitelist can access the cluster over the public network.
Click +Add. In the displayed text box, enter IP addresses or CIDR blocks that are allowed to access the cluster from the public network. Separate them using commas (,). Each value must be unique. An example of valid values: 192.168.1.1,10.0.0.0/24. Examples of invalid values: 0.0.0.0, xx.xx.xx.xx/0, 172.16.0.0-172.16.255.255, non-standard formats (e.g., 192.168.1), and duplicate values.
- If no whitelist is configured, all public IP addresses can access the cluster. However, this can be a security risk and should be avoided.
This parameter is displayed only when the security mode and public network access are both enabled for the cluster.
Private IPv4 Address
Private IPv4 address and port number of a cluster. If the cluster has only one node, the IP address and port number of the only 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.
