Alibaba Cloud Elasticsearch allows you to monitor clusters and customize alert thresholds. If an alert is detected, the system notifies you of the alert by sending a text message. To ensure the stability of your Elasticsearch cluster, we recommend that you configure monitoring and alerting. This way, the system can monitor items in real time, such as cluster status and disk usage. You can check text messages in time and take measures in advance.

ClusterStatus | Required. This metric checks the cluster status. Green indicates that an Elasticsearch cluster is in a normal state. Yellow or red indicate that an Elasticsearch cluster is in an abnormal state. |
NodeDiskUtilization(%) | Required. Set the threshold to a value that is less than 75%. The upper limit is 80%. |
NodeHeapMemoryUtilization(%) | Required. Set the threshold to a value that is less than 85%. The upper limit is 90%. |
NodeCPUUtilization(%) | Optional. Set the threshold to a value that is less than or equal to 95%. |
NodeLoad_1m | Optional. Set the threshold to a value that is 80% of the number of CPU cores per node. |
ClusterQueryQPS(Count/Second) | Optional. Set the threshold based on the actual test result. |
ClusterIndexQPS(Count/Second) | Optional. Set the threshold based on the actual test result. |
Note The monitoring and alerting feature is enabled for your Elasticsearch cluster by default.
You can view historical monitoring data on the Cluster Monitoring page of your cluster.
Only monitoring information that is generated over the last month is displayed.
