- Insights pattern – Tracks challenge patterns over the previous 30 days, serving to you determine rising issues and observe decision progress. This pattern evaluation turns into significantly invaluable when monitoring the impression of operational modifications or troubleshooting recurring points.
- Present open insights – Exhibits the rely and severity breakdown of at the moment lively insights throughout your clusters.
- OpenSearch service clusters – Lists all domains with their important statistics reminiscent of well being standing, insights rely, nodes, shards, and lively queries.
- High insights by severity – Prioritizes points that want rapid consideration. Every perception comes with a transparent description and particular suggestions, reworking advanced monitoring knowledge into actionable duties. This prioritized view helps groups can deal with important points first, whether or not they’re addressing shard dimension issues, disk area 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 important points from a single dashboard.
Cluster well being
Whenever 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, 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 too can evaluate 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 reminiscent of low disk area 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 challenge reveals an in-depth evaluation full with root trigger identification and particular remediation steps. The desk consists of essential metadata reminiscent of technology timestamps, severity ranges, advice counts, and present standing, so customers can prioritize and tackle points successfully.
Perception particulars
Each perception gives 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 checklist of affected assets.
The detailed view features a useful resource map that exactly identifies every impacted node and index, displaying important data reminiscent of node IDs, shard counts, and the indices contributing to the difficulty.
The suggestions are organized into two ranges: cluster-level suggestions tackle general structure enhancements, reminiscent of scaling your cluster or adjusting international shard allocation settings. Index-level suggestions present particular actions for particular person indices—for instance, you may 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 at the very least 5 days outdated, making them ultimate candidates for heat storage to cut back the lively shard rely. All of this steering is accessible 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 evaluate Node, Index, Shard, and Question particulars for a selected cluster. These views current important metrics reminiscent of 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 important 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 high N shards and queries working on every node.
This view helps you determine 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 displaying 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, 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 exhibits efficiency metrics aggregated on the index stage. For every index, you’ll be able to monitor doc rely and storage dimension, search latency and charge, indexing latency and charge, and entry high N queries affecting the index. This attitude is efficacious for understanding which indices are driving cluster load and figuring out optimization alternatives on the index configuration stage.
Shard view
The Shard view tab gives probably 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 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 reside 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 High-N queries).
