The Redfish special agent now supports devices that use the Redfish Sensor resource model instead of the older Power and Thermal resources. This notably includes NVIDIA MGX baseboards running OpenBMC.
What changed
The agent auto-detects which resource model the device exposes and fetches the appropriate sections automatically. Previously, devices using the Sensor resource model produced no chassis monitoring data.
NVIDIA is now recognized as a Redfish vendor. Devices from other vendors that also expose the Sensor resource model will work as well.
Four new sections are available in the Redfish Compatible Management Controller rule: Sensors, Thermal Subsystem, Power Subsystem, and Environment Metrics. Thresholds reported by these devices are picked up automatically by existing sensor checks.
Existing Redfish monitoring setups are not affected. Already supported devices continue to work exactly as before.
