# Cluster-Level Breakdown
The **Cluster Level Breakdown** gives you an in-depth view of your Kubernetes cluster's cost and efficiency. It helps you analyze how your infrastructure spend is distributed, how efficiently your workloads are running, and where savings opportunities exist. Everything is designed to help you take action at the cluster level.
From overall spend to granular inefficiencies in compute, storage, and networking, everything you need to take control is right here.
## Getting Started
To open a detailed view of any cluster, just click on the **cluster name** from the main Kubernetes Visibility page.
{% hint style="warning" %}
You’ll only see this breakdown for clusters that are **actively connected** to OneLens.
{% endhint %}
Once you're inside, you'll find four tabs that break down every aspect of your cluster:
* [**Summary**](#summary-your-starting-point)
* [**Cost Analysis**](/observe-visibility-and-insights/service-cost-monitoring/kubernetes-visibility/cost-and-node-analysis.md#cost-analysis)
* [**Node Analysis**](/observe-visibility-and-insights/service-cost-monitoring/kubernetes-visibility/cost-and-node-analysis.md#node-analysis)
* [**Workloads**](/observe-visibility-and-insights/service-cost-monitoring/kubernetes-visibility/workload-drilldown.md)
Each tab gives you a different dimension of your cluster's behavior.
## Quick Cluster Snapshot
At the very top of the breakdown, you’ll see key identifiers to orient yourself and make sure that you stay in right environment:
* **Cluster Name**
* **Status** (connected or disconnected)
* **Kubernetes Version**
* Associated **Account** and **Region**
* Any applied **Tags**
{% hint style="success" %}
### Set Your Timeframe Filter
Use the **date range selector** to define the time window for all metrics and charts. Whether you're reviewing monthly spend, analyzing a spike from last week, or tracking changes after an optimization—this control keeps your analysis focused and relevant.
{% endhint %}
## Summary: Your Starting Point
The **Summary** tab gives you a bird’s-eye view of what’s happening in your cluster. If you’re looking for a quick health check on how your resources are being used, this is the place to start. It has the following metrics:
* **Total Cost** shows you the complete spend for the selected period.
* **Cost Delta** compares it with the previous period so you can spot increases or reductions.
* **Potential Savings** surfaces estimated cost reductions based on identified inefficiencies.
* **Cluster Efficiency** gives you a score that reflects how much of your cost is actively contributing to workloads.
### Cluster Cost Breakdown
This section helps you understand how your total cluster cost is allocated across key categories:
* **Utilized Cost** – cost directly tied to workloads actively consuming resources
* **Unused Cost** – cost from idle or underutilized resources
* **Cluster Management** – operational overheads required to run the cluster
* **Extended Support** – additional service-related costs (like EKS extended support)
This breakdown gives you a clean view of what you're paying for—and whether it's returning value.
### Utilized vs Unused Cost Breakdown
To go deeper, the **Utilized Cost Breakdown** and **Unused Cost Breakdown** let you analyze each of these cost types across major resource classes:
* **Compute**
* **Networking**
* **Storage**
By seeing both actively utilized and idle costs side-by-side, you get a full picture of how your infrastructure is performing—and where adjustments can lead to real savings.
### Cluster Efficiency Breakdown
Efficiency is a combination of how your nodes, workloads, storage, and networking are performing. This breakdown shows you each dimension individually:
* **Nodes Efficiency** – how well CPU and memory are being used on your nodes
* **Workloads Efficiency** – whether workload requests align with actual usage
* **Storage Efficiency** – whether provisioned storage matches real demand
* **Networking Efficiency** – how effectively your allocated bandwidth is used
These metrics highlights the exact area that needs optimization.
### Efficiency Trend
The **Efficiency Trend** chart helps you track how your cluster’s performance is evolving. Use it to validate the impact of recent changes, monitor improvement over time, or detect regressions before they grow into larger issues.
## What’s Next?
The **Summary** tab gives you a complete overview of the cluster—but to go deeper, you can explore the other tabs of the Cluster Level Breakdown. Each has its own dedicated page to help you focus on what matters most:
* Head to the [Cost & Node Analysis](/observe-visibility-and-insights/service-cost-monitoring/kubernetes-visibility/cost-and-node-analysis.md) page for detailed cost trends and per-node metrics.
* Visit the [Workload Drilldown](/observe-visibility-and-insights/service-cost-monitoring/kubernetes-visibility/workload-drilldown.md) page to analyze workload-specific usage, efficiency, and waste.
