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

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.
