Viewing the Basic Information of a ClickHouse Cluster

You can monitor and manage the clusters you create. On the CloudTable management 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** Cluster information
Parameter	Description
Cluster Name	Cluster name specified when a cluster is created.
Cluster ID	Cluster ID.
Cluster Status	Cluster status information.
Version	Kernel version of the cluster.
Access Address	Address for accessing the cluster. You can click to copy the access link to the clipboard.
Access Address Port	Port for accessing the cluster. HTTP port: 8123 TCP port: 9000 HTTPS port: 8443 Secure TCP port: 9440
Billing Mode	Billing mode of the cluster. Pay-per-use Yearly/monthly
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.
Database Engine	A core service used to store, process, and protect data.
Channel Status	Whether secure channels are enabled.
Enable Secure and Non-secure Channels	This parameter is displayed if secure channels are not enabled.
Enable Hot/Cold	"No" indicates that the cold and hot data separation feature is disabled, and "Yes" indicates that the cold and hot data separation feature is enabled.
Storage Resource Name	Name of the cold and hot data separation data storage resource: hot_to_cold.
Cold and Hot Storage Policy	Should a node's total storage capacity surpass the predefined threshold, data stored prior to the threshold is prioritized for migration to cold storage.
Used Cold and Hot Storage Capacity	Used storage capacity of cold data.
Client	Currently, the ClickHouse component has two types of clients: old and new. For a new client, the client identifier displays 'New.' Conversely, for existing clients, the identifier displays 'Old.'

**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 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** Compute node parameters
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: 8U32G 16U64G 32U128G 32U256G 64U256G 128U512G
Storage	Select the disk specifications and capacity of the Clickhouse compute node. Available storage specifications: High I/O Ultra-high I/O Extreme SSD The capacity ranges from 500 GB to 10,000 GB per node.
Nodes	Set the number of nodes in a cluster. The value ranges from 2 to 20.

**Table 4** ZooKeeper node parameters
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 8U32G 16U64G 32U128G
Storage	Select the disk specifications and capacity of the Clickhouse compute node. Available storage specifications: General-purpose SSD Ultra-high I/O Extreme SSD The capacity ranges from 100 to 1000.
Nodes	Number of nodes in a cluster. The default value is 3.
