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 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. CAUTION:
|
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. |
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. |
Viewing Basic Cluster Information
- Log in to the CSS management console.
- In the navigation pane on the left, choose Clusters > Elasticsearch.
- In the cluster list, click the name of the target cluster. The cluster information page is displayed.
- On the Overview tab, check the cluster's basic information, configuration, and node information.
Table 2 Cluster information Type
Parameter
Description
Cluster Information
Name
Custom cluster name.
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 changed.
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.
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.
Cluster Status
Current status of a cluster
Task Status
Current task status of a cluster. If there is no ongoing task, -- 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 a cluster belongs
Current Subnet
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:Make sure the security group allows port 9200 in the inbound direction. Incorrect security group configuration may make the cluster inaccessible. Exercise caution when performing this operation.
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.
Reset Password
This parameter is available only for security-mode clusters.
Click Reset to change the admin password for a security-mode cluster.
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.
Enterprise Project
Enterprise project that a cluster belongs to.
You can click a project name to check the basic project information.
Public IP Address
Public IP address that enables public network access. It is displayed only for security-mode clusters.
- 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.
Access Control
Whether to enable access control for a cluster. This parameter is displayed only for clusters with public network access enabled.
- Enabled: Only IP addresses on 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 access control and the whitelist used for it.
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 HTTPS for a cluster.
- If HTTPS is disabled, the cluster uses HTTP instead.
- If it is enabled, HTTPS is used for cluster access. Only security-mode clusters support HTTPS. If HTTPS Access is enabled, you can click Download Certificate to obtain the CER certificate used for access control. Currently, the security certificate cannot be used in a public network environment.
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.
