Chapter 2. Power monitoring for Red Hat OpenShift release notes
Power monitoring is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
Power monitoring for Red Hat OpenShift enables you to monitor the power usage of workloads and identify the most power-consuming namespaces running in an OpenShift Container Platform cluster with key power consumption metrics, such as CPU or DRAM, measured at container level.
These release notes track the development of power monitoring for Red Hat OpenShift in the OpenShift Container Platform.
For an overview of the Power Monitoring Operator, see About power monitoring.
