Amazon OpenSearch Service adds new Cluster Insights for faster diagnosis of cluster status - devamazonaws.blogspot.com
Amazon OpenSearch Service has expanded Cluster Insights with 17 new insights that identify the root causes behind Red and Yellow cluster status and provide actionable recommendations to resolve them. These insights cover resource exhaustion scenarios including JVM out-of-memory, sustained CPU saturation, as well as configuration issues such as zone imbalance, and misconfigured replica counts. Previously, when a cluster entered Red or Yellow status due to unassigned shards, diagnosing the underlying cause required manually correlating multiple metrics across nodes and availability zones. With these new insights, OpenSearch Service automatically identifies the specific resource constraint or misconfiguration responsible and provides tailored recommendations — such as scaling up instance types, increasing disk capacity, or correcting shard allocation settings — so you can restore cluster stability faster. Six new Critical-severity insights detect conditions causing primary shards to ...
