The Intelligent Maintenance feature of Alibaba Cloud Elasticsearch provides cluster health diagnostics. After you enable Intelligent Maintenance, the system automatically diagnoses your cluster every morning and generates a diagnostic report. You can also manually trigger a diagnostic up to five times per day. The Cluster Overview and Previous Reports pages help you continuously monitor your cluster health.
To perform cluster operations diagnostics through natural language conversations, use Elasticsearch AI Assistant (ES Agent). ES Agent provides an AI-driven interactive operations experience with capabilities such as slow query analysis, exception diagnosis, root cause localization, and capacity planning. For more information, see ES Agent intelligent operations assistant user guide.
