Viewing Basic Cluster Information

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

On a cluster's Basic Information page, you can view the following information:

Cluster Information: Table 1 lists the related parameters.
Database Attribute: Table 2 lists the related parameters.
Node Configuration: Table 3 lists the related parameters.
Network: Table 4 lists the related parameters.

**Table 1** Cluster 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.
Cluster ID	ID of the cluster.
Nodes	Number of nodes in the cluster.
Cluster Version	Cluster version information.
Used Storage Capacity	Used storage capacity of the cluster.
Created	Time when the cluster was created.
Last Snapshot Created	Time when the last snapshot was created.
Maintenance Window	Maintenance window of the cluster. You can click Configure on the right of Maintenance Window to configure the maintenance window. For more information, see Configuring the Maintenance Window.

**Table 2** Database attribute parameters
Parameter	Description
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.
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 for accessing the cluster database over the public network or private network. The host port is specified when a cluster is created and used to listen to client connections.
Connection String	Connection string. You can click View Details to check the data warehouse connection information. Its value can be: JDBC URL (Private Network). In the private network environment, you can use the JDBC URL (private network) to connect to the cluster when developing applications. JDBC URL (Public Network). In the public network environment, you can use the JDBC URL (public network) to connect to the cluster when developing applications. ODBC URL. In GaussDB(DWS), you can use an ODBC driver to connect to the database. The driver can connect to the database on an ECS or over the Internet.
Private Network Domain Name	Name of the domain for accessing the database in the cluster over the private network. The private network domain address is automatically generated when a cluster is created. When you access a data warehouse cluster using a domain name, the domain name resolver provides the load balancing function. 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 workloads will be processed on a single CN.
Public Network Domain Name	Name of the domain for accessing the database in the cluster over the public network.
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 Bind EIP to bind an EIP to the cluster. If an EIP is bound during cluster creation, click Unbind EIP to unbind the EIP.

**Table 3** Node configuration
Parameter	Description
Node Flavor	Node flavor of the cluster.
Node Specifications	Specifications of the node flavor.

**Table 4** 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.
