- Insights pattern – Tracks problem patterns over the previous 30 days, serving to you establish rising issues and monitor decision progress. This pattern evaluation turns into notably beneficial when monitoring the impression of operational modifications or troubleshooting recurring points.
- Present open insights – Reveals the depend and severity breakdown of at present energetic insights throughout your clusters.
- OpenSearch service clusters – Lists all domains with their very important statistics corresponding to well being standing, insights depend, nodes, shards, and energetic queries.
- Prime insights by severity – Prioritizes points that want speedy consideration. Every perception comes with a transparent description and particular suggestions, remodeling advanced monitoring knowledge into actionable duties. This prioritized view helps groups can deal with crucial 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 possibly can assess cluster well being, establish traits, and take motion on crucial points from a single dashboard.
Cluster well being
If you select a selected cluster from the OpenSearch domains on the Cluster insights – Overview web page, you will note cluster-specific particulars together with well being standing, energetic 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 evaluate the configuration greatest practices adopted by area throughout resiliency and safety areas.
The decrease part comprises 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 corresponding to low disk house and shard depend issues, in addition to medium-severity considerations which will impression cluster efficiency.
Every perception entry serves as an interactive aspect – deciding on any problem reveals an in-depth evaluation full with root trigger identification and particular remediation steps. The desk consists of necessary metadata corresponding to era timestamps, severity ranges, advice counts, and present standing, so customers can prioritize and deal with points successfully.
Perception particulars
Each perception presents detailed evaluation and actionable suggestions. Take the Shard Depend perception for example: deciding on 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 based mostly 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 crucial info corresponding to node IDs, shard counts, and the indices contributing to the problem.
The suggestions are organized into two ranges: cluster-level suggestions deal with general structure enhancements, corresponding 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 solutions 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 supreme candidates for heat storage to scale back the energetic shard depend. All of this steering is obtainable immediately 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 possibly can evaluate Node, Index, Shard, and Question particulars for a selected cluster. These views current crucial metrics corresponding 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 crucial metrics for every node together with warmth rating indicating general node well being, useful resource utilization (CPU, reminiscence, disk), search and indexing latency and charges, together with fast hyperlinks to view prime N shards and queries working on every node.
This view helps you establish 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 displaying useful resource utilization traits over time. Moreover, you possibly can click on the highest N shards hyperlink to navigate on to the Shard View, robotically 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 possibly can monitor doc depend and storage dimension, search latency and charge, indexing latency and charge, and entry prime N queries affecting the index. This attitude 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 presents essentially 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 stress metrics (CPU, reminiscence), together with search and indexing latency per shard. This detailed view lets you 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 stay dashboards that break down execution stats, CPU and reminiscence utilization, and completion progress for each question. This helps monitor which queries are driving the largest useful resource consumption (the Prime-N queries). With intuitive donut charts and scoreboards displaying distribution by node, index, and consumer, this interface helps operators to rapidly pinpoint efficiency bottlenecks and heavy workloads, supporting focused optimization and assured scaling choices.
Question insights
