Viewing Basic HBase Cluster Information

You can monitor and manage the clusters you create. On the CloudTable console, click Cluster Management. In the cluster list, locate the cluster to be viewed and click the cluster name to access the basic information page. You can view the cluster information and network configurations.

Table 1 and Table 2 describe parameters about basic cluster information.

**Table 1** Cluster information
Parameter	Description
Cluster Name	Name of a cluster. Set this parameter when creating a cluster.
Cluster ID	Cluster ID
Cluster Status	Cluster status information
Used Storage Capacity	Used storage capacity
Billing Mode	Billing mode of the cluster
Version	Cluster kernel version
Created	Time when a cluster is created
Enterprise Project	You can group related cloud resources (for example, resources used for the same purpose) and manage them by enterprise project. NOTE: You can delete a user that was authorized to manage an enterprise project if the enterprise's business has changed and the user should not have the permissions to manage the enterprise project. You can delete a user or multiple users. After a user that was authorized to manage an enterprise project is deleted, the user cannot manage the enterprise project. If the user needs to manage the enterprise project, authorize the user to manage the enterprise project again.
ZK Link (Intranet)	ZooKeeper address. You can click to copy the ZooKeeper link to the clipboard.
Enable Security Channel	You can check whether the security channel is enabled on the CloudTable console.
Enable Thrift Server	If No is displayed, Thrift Server is disabled. If Yes is displayed, Thrift Server is enabled and the IP address of Thrift Server is displayed.
Thrift Server IP	The visibility of this field on the cluster details page depends on the Thrift Server's status: it appears when enabled and is hidden when disabled.
Database Engine	The value is HBase.
Read-only Threshold	When data is written to the storage device after the cluster's storage usage reaches a specified threshold, the storage space may become fully utilized, potentially causing performance and functionality issues. To prevent this, it is essential to set a threshold for the cluster. Upon reaching this threshold, the cluster will switch to read-only mode, and an alarm will be triggered to prompt timely management of the cluster status. The default threshold is set at 85%, with an adjustable range from 70% to 90%.
Read-only	"Yes" indicates that the read-only threshold is reached. "No" indicates that the read-only threshold is not reached.

**Table 2** Network configuration
Parameter	Description
Region	Working area of the cluster. Set this parameter when creating a cluster.
AZ	AZ you select during cluster creation
VPC	VPC you select during cluster creation A Virtual Private Cloud (VPC) is a secure, isolated, logical network environment.
Subnet	Subnet you select during cluster creation A subnet provides dedicated network resources that are logically isolated from other networks, improving network security.
Security Group	Security group you select during cluster creation

**Table 3** Master node configuration
Parameter	Parameters
Compute	Select proper compute specifications based on service requirements. Each specification displays the CPU, memory, and recommended application scenarios of a single node. NOTE: Available compute specifications: 4U16G 8U16G 8U32G 16U32G 16U64G 32U64G
Storage	Ultra-high I/O is recommended.
Nodes	Use the default value 2.

**Table 4** Core node configuration
Parameter	Description
Compute	Select proper compute specifications based on service requirements. Each specification displays the CPU, memory, and recommended application scenarios of a single node. NOTE: Available compute specifications: 4U16G 8U16G 8U32G 16U32G 16U64G 32U64G
Storage	Select the disk specifications and capacity of the HBase compute node. NOTE: Available storage specifications: Common I/O High I/O Ultra-high I/O The capacity ranges from 400 GB to 30,000 GB per node.
Nodes	Set the number of nodes in a cluster. The value ranges from 2 to 20.
