Basic information of an Alibaba Cloud Elasticsearch cluster - Elasticsearch

Go to the cluster details page

Log on to the Alibaba Cloud Elasticsearch console.
In the left-side navigation pane, click Elasticsearch Clusters.
In the top navigation bar, select a resource group and a region.
In the Elasticsearch cluster list, click the ID of the target cluster. The cluster details page opens.

This page shows the cluster's basic information, running status, and zone and node distribution.

Basic cluster information

In the Basic Information section, you can view information such as the cluster ID, cluster type, version, and network endpoints. Click Update and Upgrade on the right to upgrade the cluster version and update the kernel.

Parameter	Description
Instance ID	The unique identifier of the cluster.
Name	By default, the cluster name is the same as the cluster ID. You can customize the name during creation or change it later. The name can be used to search for the cluster.
Version	Supported versions include `8.17`, `8.15`, `8.13`, `8.9`, `8.5`, `7.16`, `7.10`, `7.7`, `6.8`, `6.7`, `6.3`, `5.6`, and `5.5`. If the current version does not meet your business requirements, you can upgrade the version.
Cluster Type	Valid values: Vector Enhanced Edition, Kernel-enhanced Edition, and Standard Edition. Different cluster types provide different features.
Control Architecture Type	The network architecture of the ES cluster: Cloud-native Control Architecture (v3): The V3 network architecture. The V3 architecture offers significant improvements in feature iteration, system stability, and security. We recommend that you upgrade your V2 architecture to V3 as soon as possible to access more powerful features and a better service experience. Basic Control Architecture (v2): The legacy V2 network architecture.
Region	The region where the cluster is deployed.
Zone	The zone where the cluster is deployed.
VPC	The VPC to which the cluster belongs.
vSwitch ID	The vSwitch to which the cluster belongs.
Internal Endpoint	The endpoint for accessing the ES cluster from an ECS instance within the same VPC.
Internal Port	The console displays port 9200. This port uses the HTTP or HTTPS protocol for communication between clients (such as browsers, applications, and Kibana) and the Elasticsearch cluster. Additionally, Alibaba Cloud Elasticsearch 5.x clusters also support the TCP-based port 9300 for internode communication. Alibaba Cloud Elasticsearch 6.0 and later do not support port 9300 access with a Transport Client. You must use a `5.x` cluster to access port 9300.
Public Endpoint	The endpoint used to access the ES cluster over the internet.
Public Port	This parameter is displayed only after you enable the Public Endpoint. The supported port numbers are the same as those for the internal port.
Protocol	HTTP is used by default. You can switch to HTTPS.
Resource Group Name	The name of the resource group to which the cluster belongs. Resource groups allow you to organize and manage resources under an Alibaba Cloud account. You can use them to centrally manage cloud resources from multiple regions.
Resource Group ID	The ID of the resource group to which the cluster belongs.
Tag	The tags attached to the cluster. You can use tags to classify and manage clusters.

Cluster running status

In the Cluster Statistics section, you can view the cluster's current status and billing method.

Parameter	Description
Status	The status of the cluster. Valid values: Normal (Green): The cluster is healthy. Initializing (Yellow): The cluster is undergoing a change, such as an upgrade. Interrupt Change (Red): A change operation on the cluster has been interrupted. Invalid (Gray): The cluster is unavailable.
Billing Method	The billing method of the cluster. Valid values: Subscription (prepaid) and Pay-as-you-go. Subscription: You can click Renew on the right to renew your cluster. The minimum renewal period is one month. Pay-as-you-go: You can click Switch to Subscription on the right to change the billing method.
Created At	The time when the cluster was created.
Maintenance Window	The time window during which Alibaba Cloud performs maintenance. The default window is 02:00–06:00. You can set a custom maintenance window.

Cluster health status

View cluster health in two ways:

Use the console

In the Node Visualization area on the Basic Information page, hover over the Cluster icon to view the cluster Status.

For a cluster health report, click Intelligent O&M.

Note
Cluster and node status may not reflect real-time state during configuration changes. Check health status only after the cluster stabilizes.
Use an API

Use the Health API to check cluster health.
```
GET /_cluster/health
```

Node information

The Node Visualization area displays zone distribution and individual node details.

Hover over a zone to view its status.
Node colors indicate health status based on CloudMonitor utilization thresholds. For details, see Metric description and suggestions for handling exceptions.
- Red: Alert.
- Yellow: Warning.
- Green: Normal.
- Gray: Unknown (no recent data).
Hover over a node to view its details.
Note
- When the Node Status is red, yellow, or gray, a diagnostic prompt appears. Click Intelligent O&M Diagnosis to go to the Intelligent O&M > Cluster Diagnostics page to diagnose the cluster.
- Click Restart to restart the cluster or a node.
Click the icon to switch the view and display node specifications, node count, and storage capacity by node type.
Click Configuration Change to scale in nodes, scale up, or scale down the cluster.

Node configuration information

In the upper-right corner of the Node Visualization area, click the icon to view node configurations in a list.

Each parameter is described in node configurations of an Elasticsearch instance.

Change records

After you change the configuration, restart the cluster, or scale an Elasticsearch instance out or in, you can track the progress and status of these changes on the Change Records page. This page also provides a history of all changes made to the instance within the last 30 days.

In the left-side navigation pane, click Change Records. On this page, you can view the progress and status of ongoing changes or review the details of changes within a selected time period.

查看变更记录

Note

By default, the page shows change records from the last 24 hours. You can also choose to view records from the last 7 days, last 30 days, or a custom time range. The maximum history available is 30 days.

Parameter	Description
Change Start Time	The time when a user-initiated change to the instance began.
Change Type	The type of change made to the cluster, such as creating an instance, restarting an instance, or changing the cluster configuration.
Changed By	The ID of the Alibaba Cloud account or RAM user that initiated the change.
Change Status	In progress: The change is being applied. Please wait. Completed: The change was successfully applied. Pause Change: The change is paused. If you did not manually pause the change, click View Logs to find the cause.
Change End Time	An end time is displayed only for changes with the status of Change Status.
Actions	Show Details: Click Show Details to view basic change information, the change type, and a before-and-after comparison on the Change Details page. Note Some parameters on the Change Details page are displayed with their internal system names. For details, see the documentation for the corresponding change operation. For example, for a change that modifies YML parameters, see Configure YML parameters. View Log: Click View Log to view the instance's operation logs on the Logs page. For more information, see Query logs.
