Basic information of an Alibaba Cloud Elasticsearch cluster-Elasticsearch(ES)-阿里云帮助中心

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. If a zone fails or has insufficient resources, migrate or fail over the zone.
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.

Indexing Service write and hosting information

Available only for Advanced Edition Alibaba Cloud Elasticsearch V7.10 instances with Indexing Service.

On the Indexing Service card, click Write Throughput on Current Day to view the trend chart for Average Write Throughput per Hour. Click View Monitoring Details for detailed monitoring data.
On the Indexing Service card, click Data Written to Hosted Indexes to view the trend chart for Data Written to Hosted Indexes on Current Day. Click Go to Index Management Center for index-level usage details.

OpenStore storage information

Available only for Alibaba Cloud Elasticsearch V7.10 instances.

Optional: Enable Enable OpenStore.

Skip this step if OpenStore was enabled during purchase. Purchase page parameters (Advanced Edition).
1. In the OpenStore storage module, turn on the usage switch.
2. In the dialog box that appears, click Enable it now..
  Important
  
  If the cluster has cold data nodes not using OpenStore, the OpenStore module is hidden and switching to OpenStore storage is not supported.
  
  If the instance version is outdated, a prompt to upgrade appears when enabling OpenStore. Upgrade the instance version first. Upgrade versions.
3. On the upgrade page, enable OpenStore, select the terms of service, and click Buy Now. Complete the purchase and return to the OpenStore storage module.
  
  Upgrade cluster configurations.

In the OpenStore storage module, view the storage information.

View the Storage Usage As Of Yesterday and the Current Real-time Estimated Usage.

Parameter	Description
Storage Usage As Of Yesterday	Actual OpenStore storage usage as of yesterday, used for metering and billing.
Current Real-time Estimated Usage	An estimate based on real-time index size. May differ from the billed value. For monitoring only.

Click Usage Details to go to the Index Management page of the Index Management Center and view the indexes in OpenStore storage.

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.

The Change Records page shows only the change history of an instance for the last 30 days. To view records older than 30 days, go to the Alibaba Cloud Elasticsearch console. In the left-side navigation pane, click Operation Records to go to the Operation Records page.

Note

The Change Records feature is not available for Elasticsearch 7.16 instances or for any instances in the China (Chengdu) and China (Guangzhou) regions.

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.
