E-MapReduce:View the instance list and details of an instance

Prerequisites

A StarRocks instance is created. For more information, see Create an instance.

View the instance list

1. Go to the instance list page.

   1. Log on to the EMR console.

   2. In the left-side navigation pane, choose EMR Serverless > StarRocks.

   3. In the top navigation bar, select a region based on your business requirements.

2. On the Instance List page, you can view all your instances and the operations that you can perform on each instance.

   Parameter	Description
   Instance ID/Name	The ID and name of the instance.
   Status	The status of the instance.
   Billing Method	The billing method of the instance.
   Instance Type	Includes storage-compute integrated and storage-compute separated types.
   Tag	Tags help you identify and manage your resources.
   Actions	The operations that you can perform on the instance, including the following: Connect: Connect to an existing StarRocks instance. For more information, see Use EMR StarRocks Manager to connect to a StarRocks instance. Renew: Only subscription instances can be renewed. For more information, see Renewal policy. Restart: Restart an instance for instance maintenance. For example, you can restart your instance for system updates, configuration changes, or other situations where a service restart is required to ensure that the new settings take effect. Warning Instance restart may cause a transient disconnection. To protect your business from being affected, make sure that the client is ready for the restart based on a retry mechanism. Release: Release an instance to prevent unnecessary costs if you no longer require the instance. Important If you release an instance, the instance and all resources in the instance are deleted. The deletion operation is irreversible. Proceed with caution.

View the details of an instance

1. On the Instance List page, click the name of the instance.

2. On the Instance Details tab, view the details of the instance.

   Section	Description
   Basic Information	Displays the basic information about the instance, including the instance ID, instance name, creation time, zone, billing method, virtual private cloud (VPC), vSwitch, and security group ID.
   Security Configuration	You can configure network whitelists, reset passwords, and perform other operations.
   Version Information	Displays the configuration information of the instance, including the instance edition, major version, and minor version.
   Manager Agent	Manager Agent is the agent service that StarRocks Manager uses to connect to instances. It is deployed in the FE by default. If your FE has high load pressure or you have higher stability requirements for StarRocks Manager, you can enable independent Manager Agent resources. For more information, see Manage Manager Agent.
   Gateway Information	Displays the default gateway information, including the internal endpoint, network type, public endpoint, and number of FE nodes. If you are using a storage-compute separated instance and want to allocate independent gateways for different business scenarios, you can add gateways. For more information about gateways, see Manage gateways.
   FE Details	Displays the details of frontend nodes (FEs), including specifications, storage size, number of nodes, storage type, internal endpoint, public endpoint, and port number.
   BE Details or CN Details	You can view the details of backend nodes (BEs) or compute nodes (CNs), such as the specifications, number of nodes, and the internal endpoint, on the Warehouse tab. For more information about compute groups, see Compute groups.
