   Type	Parameter	Description
   Cluster Information	Name	Cluster name. The name can be customized. You can click on the right to change the cluster name.
   	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.
   	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.
   	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.

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.
   	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. Disabled: The HTTP protocol is used for cluster access. Enabled: The HTTPS protocol is used for cluster access. Only security 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.
   	Private Network 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.
   Node	Node Specifications	Specifications of nodes in a cluster
   	Node Storage Type	Storage capacity and storage type of nodes in a cluster
   	Nodes	Number of nodes in a cluster
