- Prime insights by severity – Prioritizes points that want rapid 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 measurement 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, determine tendencies, and take motion on crucial points from a single dashboard.
Cluster well being
Once you select a selected cluster from the OpenSearch domains on the Cluster insights – Overview web page, you will notice 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 measurement. You may as well assessment the configuration finest 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 similar to low disk house and shard depend issues, in addition to medium-severity considerations which will affect cluster efficiency.
Every perception entry serves as an interactive aspect – choosing any concern reveals an in-depth evaluation full with root trigger identification and particular remediation steps. The desk consists of necessary metadata similar to technology timestamps, severity ranges, advice counts, and present standing, so customers can prioritize and deal with points successfully.
Perception particulars
Each perception provides 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 measurement, 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 crucial data similar 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, similar to scaling your cluster or adjusting international shard allocation settings. Index-level suggestions present particular actions for particular person indices—for instance, you may see recommendations to maneuver idle shards to UltraWarm storage. These are shards with none search or indexing operations for the final 10 days and are a minimum of 5 days outdated, making them perfect candidates for heat storage to scale back the lively shard depend. All of this steering is accessible instantly 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 possibly can assessment Node, Index, Shard, and Question particulars for a selected cluster. These views current crucial metrics similar 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 crucial 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 displaying useful resource utilization tendencies over time. Moreover, you possibly can click on the highest N shards hyperlink to navigate on to the Shard View, mechanically 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 measurement, search latency and price, indexing latency and price, 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 provides 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 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.
