Node group view — Self-hosted 2.0
This view provides a comprehensive and granular breakdown of all node groups within a cluster. It facilitates immediate identification of resource inefficiencies, enables quick prioritization of optimization tasks for optimal results, and unlocks further deep investigation.
Node group view
Data table
Node group <none> contains nodes whose labels were not identified (for example, custom labels). In that case, we recommend you group such nodes manually by configuring the Label Customizations Profile.
| Column | Description |
|---|---|
| Node Group | This displays the Node Group Name. To sort or filter data, click on a column title or use a drop-down list. |
| Architecture | This displays the Node Architecture (ARM, x86). You can sort or filter data by clicking on a column title or using a drop-down list. |
| Nodes (avg & max) | This displays the average and maximum number of nodes in a specific node group. Click on a column title to sort the data. |
| Reservation | Display the reservation type of nodes in the group. To sort or filter data, click on a column title or use a drop-down list. |
| Avg Cost/h | Displays the average node group cost per hour. Click on a column title to sort data. |
| Total Cost | Displays the total node group cost. Click on a column title to sort data. |
| Idle Cost | Displays the cost of the space in a node group that has never been used. Click on a column title to sort the data. |
| Potential savings | Displays the estimated dollar savings by applying node recommendations. |
| Last Seen | Displays the last time PerfectScale observed the Node Group. |
| Utilization | A visual representation of CPU and Memory Utilization (allocation, request, and usage) based on the selected usage percentile. Use a drop-down list to filter data with the needed value. |
Node Groups Total
Shows the total cost and idle of the nodes.
Diving into the node group
By clicking on the node group, you will be navigated to the Node Group Details screen. Here, you can get a detailed view of the running workloads within this group or review the distribution of node types along with relevant data for further analysis.
Once you are in the Node Group, you can easily explore the data with various levels of granularity based on your needs:
Node group - node types view
Node types within a node group
⚡️ Node recommendations
Node recommendations are not available in the following cases:
→ When Karpenter is installed in the cluster.
→ When using custom node types
Node recommendations
Node Recommendations is a powerful feature that provides actionable, data-driven insights to help you choose the optimal node type for your workloads and streamline the overall optimization process. Also, this view delivers the estimated savings you can achieve by applying the recommendations, enabling better forecasting and budget planning.
Node recommendations are optimized for steady-state workloads (e.g., Deployments, StatefulSets). Bursty workloads like Jobs or CI pipelines may yield less accurate results due to their ephemeral nature.
Click the Show button to expand the view and access the full recommendation, including the best-fit node type, its configuration spec, and how much $ you can cut by applying it.
Node recommendations expanded
- The projected impact on costs after implementing the recommendations and the percentage difference between the current and recommended costs.
- Recommended node type.
PerfectScale recommends new nodes within the same node family
- Constraints, including architecture type, instance type, GPU allocation, etc.
- Node details, including the available CPU and memory per node, recommended node count, and average cost per hour.
The price comparison between the original and recommended nodes is performed on a like-for-like basis: on-demand to on-demand and spot to spot. PerfectScale does not factor in any discounts the customer currently has on their existing nodes, as we cannot predict what discounts will apply to the recommended nodes if the change is made.
PerfectScale highly values your feedback on node recommendations — don’t forget to click the "Is this helpful?" button to let us know!

Node group details
Upper panel
Node Group indicates the name of the node group associated with the displayed data.
Optimization Policy indicates the cluster policy that specifies how your resources should be allocated to support the individual needs of your workloads. Learn more about policies here.
Timeframe allows you to check the data for a specific time period: click on the drop-down list in the upper right corner and select one of the existing options.
Seamlessly Export and effortlessly share your data by exporting it into a .csv file for further analysis.
Node Group Resources Utilization
To view data at a specific percentile, use the Utilization filter. The filter will impact both the charts and the table.

Clicking on a specific node type will navigate you to the workloads table, displaying the workloads associated with that node type.
This view is particularly helpful for identifying the most wasteful workload running on the node with the selected type and providing data-driven recommendations on how to eliminate it in a few clicks.
To explore the workload details at a deeper level, click on the specific workload to open a Zoom-in window that provides an in-depth view.
Node group - workloads view
Diving into the workloads running on a specific node enables you to seamlessly identify which workloads contribute the most to resource waste due to over-provisioning and adjust resource allocations with data-driven recommendations, creating new opportunities to optimize your underlying Kubernetes infrastructure.
