Viewing Cluster Details¶
Log in to the GaussDB(DWS) management console. In the navigation tree on the left, click Clusters. In the cluster list, locate the required cluster and click its name. The Cluster Information page is displayed.
On the Cluster 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.
Cluster name specified when a cluster is created.
Cluster running status. For details, see Cluster Status.
Parameter Configuration Status
Parameter configuration status of a cluster.
Cluster task status. For details, see Cluster Task Information.
Current node specifications.
Number of nodes in the cluster.
You can enable it as required. The Logical Clusters menu item will be displayed after you enable it.
ID of the cluster.
Cluster version information.
Time when the cluster was created.
Node flavor of the cluster.
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.
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.
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. The default naming rule is cluster name.dws.otc-tsi.de.
If the cluster name does not comply with the domain name standards, the prefix of the default access domain name will be adjusted accordingly.
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 Access Domain Names.
Private Network IP Address
IP address for accessing the database in the cluster over the private network.
Public Network Domain Name
Name of the domain for accessing the database in the cluster over the public network.
For details, see Managing Access Domain Names.
Public Network IP Address
IP address for accessing the database in the cluster over the public network.
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 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.
Database name specified when the cluster is created. When you connect to the cluster for the first time, connect to the default database.
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.
Current working zone of the cluster.
AZ selected during cluster creation.
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 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 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.
The storage class Ultra-high I/O and the storage space usage are displayed.
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 space in use, free space, and charged space of the cluster are displayed.
Cold Data Used Capacity
OBS capacity used by cold data.
The OBS capacity is updated every hour.
