Summary Tab
#38xxx
This tab provides a simplified landing page that allows you to quickly understand the optimization potential in your Kubernetes environments. Your environment's efficiency, any monthly wasted spend, are shown in the status bar at the top
The charts provide a clear breakdown of how optimization recommendations can provide immediate savings, the impact of taking those recommendations to reduce risk in your environment, and what additional waste can be safely removed once you have eliminated the identified risks.
The content on this tab is based on your selection in the tree viewer.
Figure: Locating the Summary Tab
When a single container is selected you will see the Overview and Metrics Viewer tabs.
Overall Monthly Spend
This first chart summarizes your current spend and compares this to what you should be spending based, on utilization.
Figure: Overall Monthly Spend
Efficiency Rating
The Efficiency Rating provides an indication of the health of your aggregated environment.
- A value of 1 indicates that, at an aggregate level, the environment is efficient according to the defined policy settings.
- A value less than 1 indicates potential savings opportunities due to over-allocated resources.
- A value greater than 1 indicates potential risks due to under-allocated resources. The value is indicated in red, when it is greater than 1.
Containers with unspecified values are not included in this calculation.
Inventory
This block shows you an inventory of the selected items broken down by hierarchy. Your selection in the tree viewer defines the scope of this report.

Optimization Breakdown
This bar chart shows the breakdown of your container spending:

Current Spend |
The bar shows you what you are currently spending on the infrastructure that has been selected in the tree viewer. |
|
Immediate Savings |
Immediate savings can be achieved by optimizing specific CPU or memory settings. To reduce costs, adjust the CPU Request settings only for containers within NodeGroups where "CPU Request" is the primary constraint. A container qualifies for immediate savings if the "% of Nodes with CPU Saturation" is below a predefined threshold. For example, if the threshold is set at 50%, only containers where "% of Nodes with CPU Saturation" is less than 50% should be considered. Immediate savings can be achieved by adjusting the Memory Request settings only for containers within Node Groups where Memory Request" is the primary constraint. Calculated as: Sum of immediate CPU savings + Sum of immediate memory savings |
|
Risk Removal |
Surplus CPU and memory are aggregated for all containers in the selected scope and used to determine this value. Calculated as: Sum(Surplus CPU>0 (in mcores))/1000 mcores/core *CPU unit cost/core + Sum(Surplus mem >0 (in MB))/1024 MB/GB *Memory unit cost/GB |
|
Optimal Cost |
This is what the infrastructure should cost to run the selected workloads. Calculated as ($Total Cost - $Total Estimated Waste). |
|
Additional Waste |
This is possible, additional savings that can be achieved. Calculated as ($Total Cost + Risk Removal - Immediate Savings - Optimal Cost). |
CPU Request and Memory Requests
This blocks lists the aggregated CPU and memory request for the selected scope of systems, broken down by the same optimization opportunities listed above. The values are colour-coded to easily identify savings and wasted resources.
Figure: CPU Requests and Memory Requests
The blocks to the right of the bar chart show the corresponding, aggregated CPU and memory values for the systems that fall into each category. Each block is a hyperlink that takes you to the AI Analysis Details page, with the relevant view selected.

CPU Requests are calculated as: (Sum (Total Surplus CPU Request (mCores)) /1000 mCores/Cores)
The cost is obtained by multiplying the above value by the CPU unit cost.
Memory Requests are calculated as: (Sum (Total Surplus Memory Request (MB)) /1024 MB/GB)
The cost is obtained by multiplying the above value by the memory unit cost.
