E-MapReduce:View instance list and details

Prerequisites

You have created an EMR Serverless StarRocks instance. For instructions, see Create an instance.

View instance list

1. Go to the EMR Serverless StarRocks Instance List page.

   1. Log on to the EMR console.

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

   3. In the top navigation bar, select a region.

2. The Instances page shows all your instances and their available actions.

   Parameter	Description
   Instance ID / Name	The ID and name of the instance.
   Status	The current status of the instance.
   Billing Method	The billing method for the instance, such as subscription or pay-as-you-go.
   Instance Type	The instance type, which can be storage-compute integrated or storage-compute separated.
   Tags	Tags assigned to the instance for identification and resource management.
   Actions	The following actions are supported: Connect: Connect to the StarRocks instance. For more information, see Connect to a StarRocks instance by using EMR StarRocks Manager. Renew: Only subscription instances support renewal. For more information, see Renewal policy. Restart: Restarting an instance is a common maintenance task, for example, to apply system updates or configuration changes that take effect only after a restart. Warning Restarting the instance causes a brief service interruption. Ensure that your client application has a retry mechanism to handle the interruption. Release: If you no longer need an instance, release it to avoid further charges. Important This action permanently deletes the instance and its resources and cannot be undone. Proceed with caution.

View instance details

1. On the Instances page, click the instance name.

2. The Instance Details tab shows detailed information about the instance.

   Section	Description
   Basic Information	Basic information about the instance, including the instance ID, instance name, creation time, zone, billing method, Virtual Private Cloud (VPC), vSwitch, and security group.
   Security Configuration	Security settings, such as network whitelists and password management.
   Version Information	Configuration information about the instance, such as the instance series, major version, and minor version.
   Manager agent	Manager Agent is the agent that StarRocks Manager uses to connect to the instance. By default, it is deployed on the frontend (FE) nodes. If your FE nodes experience high load or you require higher stability for StarRocks Manager, you can enable dedicated Manager Agent resources. For more information, see Manage Manager Agent.
   Gateway Information	Information about the default gateway, including the internal endpoint, network type, public endpoint, and the number of FE nodes. If you are using a storage-compute separated instance, you can add gateways to serve different business scenarios. For more information about gateways, see Manage gateways.
   FE Details	Detailed information about the FE nodes, including specifications, storage size, number of nodes, storage type, internal endpoint, public endpoint, and port.
   BE Details or CN details	The Computing Group tab provides detailed information about backend (BE) or compute node (CN) nodes, including their specifications, number of nodes, and internal endpoint. For more information about compute groups, see Compute groups.
