- Present open insights – Reveals the depend and severity breakdown of presently lively insights throughout your clusters.
- OpenSearch service clusters – Lists all domains with their important statistics similar to well being standing, insights depend, nodes, shards, and lively queries.
- Prime insights by severity – Prioritizes points that want fast consideration. Every perception comes with a transparent description and particular suggestions, remodeling advanced monitoring knowledge into actionable duties. This prioritized view helps groups can give attention to vital points first, whether or not they’re addressing shard dimension issues, disk house points, or efficiency bottlenecks.
Collectively, these sections present a complete view of your OpenSearch Service infrastructure so you’ll be able to assess cluster well being, determine developments, and take motion on vital points from a single dashboard.
Cluster well being
Whenever you select a particular cluster from the OpenSearch domains on the Cluster insights – Overview web page, you will note cluster-specific particulars together with well being standing, lively insights, and efficiency metrics. The overview part shows cluster well being together with important metrics together with depend of shards, nodes, indices, and a complete doc dimension. You may also assessment the configuration greatest practices adopted by area throughout resiliency and safety areas.
The decrease part incorporates a desk of actionable insights that presents an in depth view of present points. This desk mirrors the insights from the touchdown web page however focuses particularly on points affecting the chosen cluster. You may observe high-severity points similar to low disk house and shard depend issues, in addition to medium-severity issues which will impression cluster efficiency.
Every perception entry serves as an interactive component – choosing any difficulty reveals an in-depth evaluation full with root trigger identification and particular remediation steps. The desk contains vital metadata similar to era timestamps, severity ranges, suggestion counts, and present standing, so customers can prioritize and handle points successfully.
Perception particulars
Each perception affords detailed evaluation and actionable suggestions. Take the Shard Rely perception for instance: choosing it reveals a complete breakdown of the problem. You’ll see that your OpenSearch cluster has breached the variety of shards allowed on the nodes primarily based on its JVM heap dimension, together with an in depth checklist of affected sources.
The detailed view features a useful resource map that exactly identifies every impacted node and index, displaying vital data similar to node IDs, shard counts, and the indices contributing to the problem.
The suggestions are organized into two ranges: cluster-level suggestions handle total structure enhancements, similar to scaling your cluster or adjusting world shard allocation settings. Index-level suggestions present particular actions for particular person indices—for instance, you may see options to maneuver idle shards to UltraWarm storage. These are shards with none search or indexing operations for the final 10 days and are at the very least 5 days previous, making them very best candidates for heat storage to cut back the lively shard depend. All of this steerage is on the market straight inside the Cluster insights interface, eliminating the necessity to swap between totally different instruments or consoles.
Node, Index, Shard, and Question view
Subsequent to cluster well being, you’ll be able to assessment Node, Index, Shard, and Question particulars for a particular cluster. These views current vital metrics similar to useful resource (CPU, reminiscence, disk) utilization, search and index latency.
Node view
The Node view tab gives a complete view of particular person node efficiency throughout your cluster. This desk shows vital metrics for every node together with warmth rating indicating total node well being, useful resource utilization (CPU, reminiscence, disk), search and indexing latency and charges, together with fast hyperlinks to view high N shards and queries working on every node.
This view helps you determine nodes experiencing excessive useful resource utilization or efficiency degradation. You may drill deeper into every node by clicking on the node ID to view detailed time-based metrics exhibiting useful resource utilization developments over time. Moreover, you’ll be able to click on the highest N shards hyperlink to navigate on to the Shard View, routinely filtered to point out solely the shards working on the chosen node, permitting you to pinpoint which particular shards are contributing to efficiency points.
Index view
The Index view tab reveals efficiency metrics aggregated on the index degree. For every index, you’ll be able to monitor doc depend and storage dimension, search latency and fee, indexing latency and fee, and entry high N queries affecting the index. This angle is effective for understanding which indices are driving cluster load and figuring out optimization alternatives on the index configuration degree.
Shard view
The Shard view tab affords probably the most granular view of cluster efficiency by displaying metrics for particular person shards. Every row reveals shard ID and its assigned node, index affiliation and useful resource strain metrics (CPU, reminiscence), together with search and indexing latency per shard. This detailed view lets you pinpoint particular shards inflicting efficiency points, determine shard placement imbalances, and take focused remediation actions.
Question view
The Question view on the Cluster insights web page solves presents dwell dashboards that break down execution stats, CPU and reminiscence utilization, and completion progress for each question.
