Overview of the Elasticsearch Clusters page

The Elasticsearch Clusters page of the Alibaba Cloud Elasticsearch console displays the basic information of Elasticsearch clusters. This page also allows you to create clusters, configure alerting, add tags to clusters, update cluster statuses, export a cluster list, customize a cluster list, and manage clusters.

Log on to the Elasticsearch console. In the left-side navigation pane, click Elasticsearch Clusters to go to the Elasticsearch Clusters page. The Elasticsearch Clusters page displays all the Elasticsearch clusters that are within your Alibaba Cloud account and created in the current region. This page also allows you to perform the following operations.

Operation	Description
Create a cluster	You can click Create to go to the buy page of Elasticsearch and create an Elasticsearch cluster. For more information, see Create an Alibaba Cloud Elasticsearch cluster.
Enable or disable alerting	You can click Alarms to enable the alerting feature for Elasticsearch in the CloudMonitor console. By default, this feature is disabled. After you enable this feature, CloudMonitor creates alert rules to detect exceptions such as abnormal cluster status, high disk usage (> 75%), and high JVM heap memory usage (> 85%). These rules are applied to all Elasticsearch clusters within your Alibaba Cloud account. For more information, see Configure cluster alerting.
Add tags to clusters	If you have a large number of Alibaba Cloud Elasticsearch clusters, you can add tags to them for easy management. Each tag consists of a key and a value. You can use tag keys and values to further classify clusters. For more information, see Manage cluster tags.
Update cluster statuses	You can click the Refresh icon in the upper-right corner to update the statuses of Elasticsearch clusters. After an Elasticsearch cluster is created, it is in the Initializing state. You can click the Refresh icon to update the status of the cluster. After the value of Status for the cluster changes to Active, you can use the cluster.
