Amazon OpenSearch Service expands Cluster Insights with a new insight

Posted on: May 5, 2026

Amazon OpenSearch Service expands Cluster Insights availability to all OpenSearch versions and Elasticsearch version 6.8 and above, bringing proactive cluster health and performance visibility through the Console. In addition, a new Unused Index insight helps customers identify indices in an OpenSearch cluster that have had zero search and indexing activity over the past 30 days, and provides actionable recommendation to optimize costs.

Cluster Insights now supports expanded version coverage — customers running OpenSearch 1.0 and later, and Elasticsearch 6.8 and later, can easily identify and resolve performance and stability risks before they impact workloads. Additionally, the new Unused Index insight detects indices with no search or indexing activity and recommends migration to warm or cold storage tiers for cost optimization. These insights are available through the Console, OpenSearch Service Notifications, OpenSearch UI, and Amazon EventBridge, giving users instant visibility into cluster health along with actionable recommendations to prevent issues before they affect stability or performance.

Cluster Insights is available at no additional cost in all Regions where Amazon OpenSearch Service is available. View the complete list of supported Regions here. To learn more about Cluster Insights, refer to our technical documentation.
