    Parameter Description
    Cluster ID The unique ID of the Elasticsearch cluster.
    Name The name of the Elasticsearch cluster. By default, the name of a cluster is the same as its ID. Cluster names are configurable. You can search for clusters by name.
    Version The version of the Elasticsearch cluster. Valid values: 5.5.3, 5.6.0, 6.3.2, 6.7.0, 6.8.0, and 7.4.0.
    Notice If you want to upgrade the cluster version, you can use the version upgrade feature of Alibaba Cloud Elasticsearch. You can only upgrade Alibaba Cloud Elasticsearch clusters from V6.3.2 to V6.7.0. For more information, see Upgrade the version of a cluster.
    Cluster Type The type of the Elasticsearch cluster. Valid values: Standard and Advanced.
    Region The region where the Elasticsearch cluster resides.
    Zone The zone where the Elasticsearch cluster resides.
    VPC The Virtual Private Cloud (VPC) to which the Elasticsearch cluster belongs.
    VSwitch The VSwitch to which the Elasticsearch cluster belongs.
    Tag The tag bound to the Elasticsearch cluster. You can use tags to classify and manage Elasticsearch clusters. For more information, see Manage cluster tags.
    Protocol The protocol used by the Elasticsearch cluster. Default value: HTTP. Valid values: HTTP and HTTPS. .
    Internal Network Address The internal endpoint of the Elasticsearch cluster. In a VPC, you can use an Elastic Compute Service (ECS) instance to connect to the internal endpoint of an Elasticsearch cluster.
    Notice For security and stability purposes, we recommend that you do not connect to an Elasticsearch cluster over the Internet. You can purchase an ECS instance that resides in the same VPC as your Elasticsearch cluster and then use the ECS instance to connect to the internal endpoint of the Elasticsearch cluster.
    Internal Network Port The port used to connect to the Elasticsearch cluster over a private network. Alibaba Cloud Elasticsearch supports the following ports:
    • Port 9200 for HTTP and HTTPS.
    • Port 9300 for TCP. Only Alibaba Cloud Elasticsearch V5.5.3 supports this port.
      Note For Alibaba Cloud Elasticsearch V6.X and later, you cannot use the transport client to access port 9300.
    Public Network Access The public endpoint of the Elasticsearch cluster. To connect to an Elasticsearch cluster by using its public endpoint, turn on Public Network Access. You must enable public network access first on the Network Settings page. For more information, see Security.
    Public Network Port The port used to connect to the Elasticsearch cluster over the Internet. This parameter is only displayed after you enable Public Network Access. Alibaba Cloud Elasticsearch supports the following ports:
    • Port 9200 for HTTP and HTTPS.
    • Port 9300 for TCP. Only Alibaba Cloud Elasticsearch V5.5.3 supports this port.
      Note
      • For Alibaba Cloud Elasticsearch V6.X and later, you cannot use the transport client to access port 9300.
      • You must configure the public IP address whitelist. By default, all IP addresses are prohibited from accessing Elasticsearch. For more information, see Security.
    Status The state of the Elasticsearch cluster. An Elasticsearch cluster has the following states: Active (green), Initializing (yellow), Unhealthy (red), Paused (red), and Expired (gray).
    Billing Method The billing method of the Elasticsearch cluster. Valid values: Pay-As-You-Go and Subscription.
    Created At The time when the Elasticsearch cluster was created.
    Maintenance Window The maintenance window for the Elasticsearch cluster. The default value of this parameter is set to 02:00 ~ 06:00. You can set Maintenance Window based on your business needs. For more information, see Set a maintenance window.
    Renew

    This parameter is only displayed when Billing Method is Subscription.

    You can click Renew on the right side of Basic Information to renew the cluster. The minimum renewal period of a cluster is one month.

    Switch to Subscription

    This parameter is only displayed when Billing Method is Pay-As-You-Go.

    You can click Switch to Subscription in the lower-right corner of the Basic Information section to change the billing method. With the Switch to Subscription feature, you can change the billing method of an Elasticsearch cluster from Pay-As-You-Go to Subscription. However, no discount is offered when you change the billing method.
