- Insights development – Tracks subject patterns over the previous 30 days, serving to you establish rising issues and observe decision progress. This development evaluation turns into notably worthwhile when monitoring the impression of operational modifications or troubleshooting recurring points.
- Present open insights – Reveals the rely and severity breakdown of presently lively insights throughout your clusters.
- OpenSearch service clusters – Lists all domains with their important statistics equivalent to well being standing, insights rely, nodes, shards, and lively queries.
- High insights by severity – Prioritizes points that want speedy consideration. Every perception comes with a transparent description and particular suggestions, remodeling complicated 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 may assess cluster well being, establish developments, and take motion on vital points from a single dashboard.
Cluster well being
Once 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 rely of shards, nodes, indices, and a complete doc dimension. You may also evaluation the configuration finest 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’ll be able to observe high-severity points equivalent to low disk house and shard rely issues, in addition to medium-severity issues which will impression cluster efficiency.
Every perception entry serves as an interactive component – choosing any subject reveals an in-depth evaluation full with root trigger identification and particular remediation steps. The desk consists of vital metadata equivalent to technology timestamps, severity ranges, advice counts, and present standing, so customers can prioritize and deal with points successfully.
Perception particulars
Each perception affords detailed evaluation and actionable suggestions. Take the Shard Depend perception for example: choosing it reveals a complete breakdown of the difficulty. 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 listing of affected sources.
The detailed view features a useful resource map that exactly identifies every impacted node and index, displaying vital info equivalent to node IDs, shard counts, and the indices contributing to the difficulty.
The suggestions are organized into two ranges: cluster-level suggestions deal with total structure enhancements, equivalent to scaling your cluster or adjusting world shard allocation settings. Index-level suggestions present particular actions for particular person indices—for instance, you would possibly see strategies to maneuver idle shards to UltraWarm storage. These are shards with none search or indexing operations for the final 10 days and are no less than 5 days outdated, making them preferrred candidates for heat storage to cut back the lively shard rely. All of this steering is offered straight inside the Cluster insights interface, eliminating the necessity to change between totally different instruments or consoles.
Node, Index, Shard, and Question view
Subsequent to cluster well being, you may evaluation Node, Index, Shard, and Question particulars for a particular cluster. These views current vital metrics equivalent to useful resource (CPU, reminiscence, disk) utilization, search and index latency.
Node view
The Node view tab supplies 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 establish nodes experiencing excessive useful resource utilization or efficiency degradation. You’ll be able to 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 may click on the highest N shards hyperlink to navigate on to the Shard View, routinely filtered to indicate 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 exhibits efficiency metrics aggregated on the index degree. For every index, you may monitor doc rely and storage dimension, search latency and fee, indexing latency and fee, and entry high N queries affecting the index. This angle is efficacious 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 essentially the most granular view of cluster efficiency by displaying metrics for particular person shards. Every row exhibits 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 allows you to pinpoint particular shards inflicting efficiency points, establish 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. This helps monitor which queries are driving the most important useful resource consumption (the High-N queries). With intuitive donut charts and scoreboards exhibiting distribution by node, index, and consumer, this interface helps operators to rapidly pinpoint efficiency bottlenecks and heavy workloads, supporting focused optimization and assured scaling selections.
Question insights
Along with Cluster insights, you may also get Question insights to view the precise queries working and latencies throughout Increase, Question, and Fetch phases that gives worthwhile insights for search builders to additional fine-tune their queries.
