**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.
Logical Clusters	You can enable it as required. The Logical Clusters menu item will be displayed after you enable it.
Cluster ID	ID of the cluster.
Cluster Version	Cluster version information.
Node Flavor	Node flavor of the cluster.
Enterprise Project	Enterprise project to which a cluster belongs. You can click the enterprise project name to view and edit it on the console of the Enterprise Project service.
Time Zone	The cluster time zone affects the node OS, log files, and data warehouse. You can change the time zone for the node OS and log files, but not for the data warehouse databases. To change the time zone of the data warehouse databases, use the GUC parameter timezone. For details, see Modifying GUC Parameters of the GaussDB(DWS) 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. The default naming rule is cluster name.dws.myhuaweicloud.com. 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. For details, see Managing GaussDB(DWS) Cluster Access Domain Names.
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. If IPv6 is enabled for a cluster, both IPv4 and IPv6 private addresses will be displayed. You can use either of them as needed.
Public Network Domain Name	Name of the domain for accessing the database in the cluster over the public network. For details, see Managing GaussDB(DWS) Cluster Access Domain Names. 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 Modifying a VPC 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 Modifying a Subnet in the Virtual Private Cloud User Guide.
Security Group	Security group selected during cluster creation. After a GaussDB(DWS) cluster is created, you can change the security group. You can also add, delete, or modify security group rules in the current security group. Changing the security group of a cluster may cause brief service disruption. Exercise caution when performing this operation. For better network performance, do not select more than five security groups. To change the security group, click Modify on the right of the security group name, select the security group name to be changed, and click OK. Modifying an existing security group rule: Click the security group name to go to the security group details page. For details about security group operations, see Security Group in the Virtual Private Cloud User Guide.

**Table 4** Billing information
Parameter	Description
Billing Mode	Billing mode. Pay-per-use Yearly/Monthly
Created	Time when a pay-per-use or yearly/monthly cluster is created.
Order (for yearly/monthly billing)	Order number of a yearly/monthly cluster.
Expiration Date (for yearly/monthly billing)	Expiration time of a yearly/monthly cluster.

**Table 5** 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.
Used Cold Data Capacity (DWS 3.0 parameter)	OBS hot data capacity used by DWS 3.0.
Used Cold Partition Data Capacity	OBS capacity used by cold data. NOTE: OBS capacity usage. It is synchronized every hour.
Used Capacity of OBS Foreign Tables	OBS capacity used by the foreign tables of the default OBS server of the cluster: default_obs_foreign_table_server. NOTE: OBS capacity usage. It is synchronized every hour.

**Table 6** O&M account
Parameter	Description
O&M Account	Specifies whether to enable the cluster O&M account. Check the created O&M account. Its name format is om_user_First_eight_numbers_in_cluster_ID. The gs_role_analyze_any, gs_role_vacuum_any, gs_role_read_all_stats, and gs_role_signal_backend roles will be assigned to the account. For details, see Preset Roles.
Account Status	Displays the status of the current cluster O&M account, which can be Normal or Expired.
Expires	Indicates the expiration time of the O&M account of the current cluster.
Extend by 8h	For a normal account, its validity period is extended to 8 hours later than its expiration time. For an expired account, its validity period is extended to 8 hours later than the current time.

**Table 7** Data encryption information
Parameter	Description
Key Name	Indicates the database encryption key of the cluster when Encrypt DataStore is enabled.
Last Key Rotation Time	Indicates the time when the last encryption key is rotated when Encrypt DataStore is enabled.

Changing a Cluster Name

You can change the name of a created GaussDB(DWS) cluster.

After the cluster name is changed, the names of all nodes in the current cluster are changed accordingly.

If the cluster name cannot be changed on the console, contact technical support to upgrade the console.
If the cluster name fails to be changed, the cluster functions are not affected. You can contact technical support rectify the fault.

Constraints

If the cluster is in the Unavailable status or is performing other tasks, the cluster name cannot be changed. You can change the cluster name only after the cluster status changes to Available or the running tasks are complete.
