Viewing Cluster Details

Log in to the GaussDB(DWS) management console. In the navigation tree on the left, click Clusters > Dedicated Clusters. In the cluster list, locate the required cluster and click its name. The Cluster Information page is displayed.

On the Basic Information page, you can view the following information:

Basic Information: Table 1 lists the related parameters.
Connection: Table 2 describes the parameters.
Network: Table 3 lists the related parameters.
Storage/Backup Capacity: Table 4 describes the parameters.

**Table 1** Basic information
Parameter	Description
Cluster Name	Cluster name specified when a cluster is created.
Cluster Status	Cluster running status. For details, see Cluster Status.
Parameter Configuration Status	Parameter configuration status of a cluster.
Task Information	Cluster task status. For details, see Cluster Task Information.
Current Specifications	Current node specifications.
Nodes	Number of nodes in the cluster.
Cluster ID	ID of the cluster.
Cluster Version	Cluster version information.
Created	Time when the cluster was created.
Node Flavor	Node flavor of the cluster.
Maintenance Window	Maintenance window of the cluster.

**Table 2** Connection
Parameter	Description
Private Network Domain Name	Domain name for accessing the cluster database through the internal network. The domain name corresponds to all CN IP addresses. The private network domain address is automatically generated when a cluster is created. NOTE: If the cluster name does not comply with the domain name standards, the prefix of the default access domain name will be adjusted accordingly. Load balancing is not supported. You can click Modify to change the private network domain name. The access domain name contains 4 to 63 characters, which consists of letters, digits, and hyphens (-), and must start with a letter.
Private Network IP Address	IP address for accessing the database in the cluster over the private network. NOTE: A private IP address is automatically generated when you create a cluster. The IP address is fixed. The number of private IP addresses equals the number of CNs. You can log in to any node to connect to the cluster. If you access a fixed IP address over the internal network, all the resource pools will run on a single CN.
Public Network Domain Name	Name of the domain for accessing the database in the cluster over the public network. NOTE: Load balancing is not supported.
Public Network IP Address	IP address for accessing the database in the cluster over the public network. NOTE: If no EIP is assigned during cluster creation and Public Network IP Address is empty, click Edit to bind an EIP to the cluster. If an EIP is bound during cluster creation, click Edit to unbind the EIP.
Initial Administrator	Database administrator specified during cluster creation. When you connect to the cluster for the first time, you need to use the initial database administrator and password to connect to the default database.
Port	Port number for accessing the cluster database through the public network or private network. The port number is specified when the cluster is created.
Default Database	Database name specified when the cluster is created. When you connect to the cluster for the first time, connect to the default database.
ELB Address	To achieve high availability and avoid single-CN failures, a new cluster needs to be bound to ELB. You are advised to use the ELB address to connect to the cluster.

**Table 3** Network
Parameter	Description
Region	Current working zone of the cluster.
AZ	AZ selected during cluster creation.
VPC	VPC selected during cluster creation. A VPC is a secure, isolated, and logical network environment. After a data warehouse cluster is created, its VPC cannot be changed. However, you can edit and modify the current VPC. You can click the VPC name to go to the VPC details page to configure it. For details about VPC operations, see VPC and Subnet in the Virtual Private Cloud User Guide.
Subnet	Subnet selected during cluster creation. A subnet provides dedicated network resources that are isolated from other networks, improving network security. After a data warehouse cluster is created, its subnet cannot be changed. However, you can edit and modify the current subnet. You can click the subnet name to go to the subnet details page to configure it. For details about subnet operations, see VPC and Subnet > Modifying a Subnet in the Virtual Private Cloud User Guide.
Security Group	Security group selected during cluster creation. After a data warehouse cluster is created, its security group cannot be changed. However, you can edit and modify the current security group, and add, delete, or modify rules in it. You can click the security group name to go to the security group details page to configure it. For details about security group operations, see Security > Security Group in the Virtual Private Cloud User Guide.

**Table 4** Storage/Backup capacity
Parameter	Description
Storage	The storage class Ultra-high I/O and the storage space usage are displayed. NOTE: The used storage capacity does not include data on OBS foreign tables. It includes only GaussDB(DWS) data, including files, logs, snapshots, and indexes. The available storage space is half of the actual disk capacity.
Backup	The space in use, free space, and charged space of the cluster are displayed.
Cold Data Used Capacity	OBS capacity used by cold data. NOTE: OBS capacity usage. It is synchronized every hour.
