Background

The aim of this feature is to provide a list of tested platforms for Bare Metal environments in which power monitoring for Red Hat OpenShift has been tested, and compare results with other tools such as power meter.

Motivation

The motivation for this work is varied. On the one hand, not all hardware is providing the same APIs for power monitoring. We know RAPL is in nearly all Intel modern processors, also present in some AMD. ACPI plays a significant role for the platform power reporting too. apart from that, RedFish has shown better results when compared with power meter ones. (See OBSDA-645).

Requirements

Upon the completion of this ticket, power monitoring users shall:

• Have a list of tested platforms (consider platforms already covered by the perf and scale team and the outlined ones in OBSDA-627 for AWS, GCP etc)
• On the tested platforms, have error bars showing differences between APIs (power sources)
• The objective is for users to understand, on the tested platforms, which validity of data to expect.

This exercise only applies for workloads running on Bare Metal.

To clarify

• How to extend this effort in time?
• Will the exercise be repeated every OCP release?
