After you enable Intelligent Maintenance, the system automatically performs a diagnostic on your Alibaba Cloud Elasticsearch cluster every morning. After the diagnostic is complete, a diagnostic report is generated. In addition to the daily diagnostic, you can use the Cluster Diagnosis feature to manually diagnose your Elasticsearch cluster. You can use this feature to diagnose a cluster for up to five times a day. Each diagnostic requires about 3 minutes.
Prerequisites
