View Clusters & Cost Trends
To explore how your EKS clusters are performing and where your Kubernetes costs are going, start by accessing the Kubernetes Visibility section in OneLens. This view gives you a high-level summary of your clusters along with cost, efficiency, and potential savings signals.
How to Access It
Log in to your OneLens UI.
From the left-hand sidebar, click on Kubernetes.
You’ll land on the Clusters tab by default—this is where all discovered EKS clusters are listed and analyzed.
Clusters List
The Clusters page shows both connected and disconnected clusters discovered via CUR. Here you can see:
Key Metrics
At the top of the page, you’ll find aggregated metrics that summarize your Kubernetes usage:
Cost (Month-To-Date) – Total EKS cost incurred so far in the current month
Previous Month Cost – Total cost from the last completed billing month
Potential Savings – Estimated savings based on optimization recommendations from OneLens
Total Clusters – The number of EKS clusters currently detected from CUR
You can get a quick sense of current cloud spend trends, helping you assess how this month compares with the last and where optimization opportunities may exist.
Cluster List Table
You’ll see a table listing all the EKS clusters detected through CUR, enriched with key metadata and metrics that help you assess both cost and operational efficiency.
Each row includes:
Cluster Name – The name identified through CUR or the OneLens agent
Version – The current Kubernetes version
Status – Shows the cluster’s connectivity state:
Connected – OneLens agent is installed and actively sending data
Disconnected – Identified through CUR, but the agent hasn’t been installed yet
Deleted – The cluster has been removed from your environment but still appears in the list
Cost – Total cost attributed to the cluster for the selected time period
Potential Savings – Estimated savings based on inefficiencies and unused resources
Efficiency – A derived metric (available only for connected clusters) that reflects how effectively the cluster resources are being utilized relative to cost
Region – AWS region where the cluster is or was deployed
NOTE
Clusters marked as Deleted have been removed during the current month but still show up because they incurred costs within the ongoing billing period. They will automatically be removed from the list after the current month ends.
Hover on the delete status to see the exact date of cluster deletion.
You can click on any cluster name in the table to view its Cluster-Level Breakdown, where you'll find workload, namespace, and resource-specific insights—available for connected clusters.
To learn more about what’s available at the cluster level, visit the Cluster-Level Breakdown page.
NOTE
The data in this section is fully powered by CUR by default.
If you’d like to view data from the OneLens agent wherever it's available—such as real-time breakdowns by namespace, workload, and labels—toggle the data source switch at the top-right corner of the page.
Cost Analyzer
The Cost Analyzer tab gives you a breakdown of how your EKS costs are distributed across clusters, workloads, namespaces, and more. It functions just like the main Cost Analyzer tab in OneLens, but with a limited set of features tailored specifically for Kubernetes environments.
Prerequisites
To view meaningful data on this page:
Your CUR data must include EKS split cost allocation
Not sure if split cost allocation is enabled? Visit the Enable Split Cost Allocation for EKS guide.
Customize your view using the following:
Date Range – Select the period you want to analyze
Granularity – Choose the time resolution (e.g., daily)
Filters – Narrow the view by cluster, namespace, workload type, workload name, labels, charge type, or resource type.
Group By – Choose how to segment the cost data across:
Cluster Name
Namespace
Workload Type
Workload Name
Labels
Resource Type
Charge Type
You’ll find two primary metrics:
Total Cost – Aggregated EKS cost for the selected filters and period
Cost Delta – Change in cost compared to the previous time window
The graph helps you visualize how cost evolves over time across the selected grouping. You can toggle between two visualization styles:
Bar Chart – Ideal for distinct comparisons across groupings
Area Chart – Useful for viewing accumulated or stacked trends
If you prefer a focused view on tabular data, you also have the option to hide the graph entirely.
A tabular breakdown appears below the graph, giving you a structured view of cost by the selected grouping.
Highlight
You can toggle the cost delta display to view it as either:
Dollar ($) value
Percentage (%) change
The table can also be exported for offline use or reporting. You can choose from:
CSV – Ideal for detailed data analysis and manipulation.
Excel – Provides a structured spreadsheet version of the report.
