CostManagement

Achieve cost and resource cost visualization across multiple clusters. Administrators can intuitively understand cost distribution and resource usage in different clusters. Platform costs can be divided according to different business teams, helping each business team understand its cost allocation. This aids platform administrators in understanding the overall cost structure and taking appropriate measures to optimize resource allocation and control costs.

Glossary

Term	Explanation
Usage	The actual CPU and memory usage of container groups.
Request	The expected request amount of CPU and memory for container groups. This is the amount of resources that container groups want the system to reserve for them.
__Idle__	The idle cost of CPU and memory resources not allocated to any workloads.
Allocated	The cost of resources allocated to workloads.
Sum	In a specified time range, the sum of allocated cost and __Idle__ cost per day or per hour.
__Unmounted__	The cost of storage resources occupied by pre-created, unallocated persistent volumes (PV).
__Total__	The cumulative cost of CPU, memory, and storage resources.
__Other__	A collection of namespaces not associated with any projects.
CPU/Memory/Storage Cost	The sum of allocated cost and the corresponding __Idle__ cost for CPU, memory, and storage.

Prerequisites

In the configuration platform and Kubecost, there are three specific options for currency units, outlined as follows:

	Use Case	Solution Description
Default Option	Cost data in both the platform and Kubecost is displayed in USD.	The currency unit in both the platform and Kubecost defaults to USD, requiring no currency unit replacement or exchange rate conversion operations.
Recommended Option	Cost data in both the platform and Kubecost is displayed in CNY.	In a specified namespace on the platform, the currency unit for the platform can be set to CNY by adding a configuration dictionary (ConfigMap). Simultaneously, the currency unit in Kubecost can be set to CNY to ensure uniformity of currency in both the platform and Kubecost. Please refer to Configuring Currency Units in the Platform and Kubecost for specific details.
Other Options	Cost data in the platform and Kubecost is displayed in different currency units.	In a specified namespace on the platform, the currency unit used by the platform and the exchange rate can be set by adding a configuration dictionary (ConfigMap). Additionally, the currency unit in Kubecost can be configured separately. For details, refer to Configuring Currency Units in the Platform and Kubecost .

Please customize the hourly unit prices for CPU, memory, and storage. Log in to Kubecost, navigate to the Settings > PRICING page, and if Enable Custom Pricing is not enabled, default values will be used. If this option is enabled, fill in the actual subscription or usage prices for CPU, memory, and storage.
Deploy the CostManager plugin on the global cluster.
Deploy the Kubecost plugin on each cluster that displays cost data. The deployment and use of the Kubecost plugin depend on the Prometheus plugin. First, deploy the Prometheus plugin , and then deploy the Kubecost plugin .

General Parameters

In Platform or Cluster cost management, only the cost information of clusters that have successfully deployed the Kubecost plugin is included. In Project cost management, only the cost information of all clusters associated with the project and successfully deployed with the Kubecost plugin is included.

Parameter	Description	Calculation Formula
Total Cost	The cumulative cost of CPU, memory, and storage resources in all clusters within a specified time range.	Total Cost = CPU Cost + Memory Cost + Storage Cost (excluding disk cost) CPU Cost = The number of CPU cores in all nodes of all clusters that have successfully deployed the Kubecost plugin * CPU hourly unit price * Time. Memory Cost = Memory (in GB) of all nodes in all clusters that have successfully deployed the Kubecost plugin * Memory hourly unit price * Time. Storage Cost = Capacity of all persistent volumes (PVs) in all clusters that have successfully deployed the Kubecost plugin * Storage hourly unit price * Time. Note: Storage cost is not calculated if persistent volumes (PVs) are not bound to persistent volume claims (PVCs).
CPU Utilization Efficiency	The Usage / Request of container group CPU in all clusters within a specified time range.	CPU Usage Efficiency = The sum of Usage of all container group CPUs in all clusters that have successfully deployed the Kubecost plugin / The sum of Request of all container group CPUs in all clusters that have successfully deployed the Kubecost plugin.
Memory Utilization Efficiency	The Usage / Request of container group memory in all clusters within a specified time range.	Memory Usage Efficiency = The sum of Usage of all container group memory in all clusters that have successfully deployed the Kubecost plugin / The sum of Request of all container group memory in all clusters that have successfully deployed the Kubecost plugin.
Cost Effectiveness	The cumulative cost of CPU and memory Usage compared to the cumulative cost of allocation in all clusters within a specified time range.	Cost Efficiency = ((CPU Usage Efficiency * CPU Allocated Cost) + (Memory Usage Efficiency * Memory Allocated Cost)) / (CPU Allocated Cost + Memory Allocated Cost) CPU Allocated Cost = max(Usage, Request) * CPU hourly unit price * Time. Memory Allocated Cost = max(Usage, Request) * Memory hourly unit price * Time.
Cost Breakdown	Splits the total cost in the platform into resources, primarily CPU, memory, and storage.	-
Cost Trends	Displays the total, __Idle__, and allocated cost information for the selected time range.	-

Platform Cost Management
