If you monitor Redfish devices that use newer BMC firmware, you now get performance data for all sensor types — not just temperature and humidity. This means graphs and thresholds for:
- Fan speed (RPM or %)
- Voltage (V)
- Current (A)
- Power consumption (W)
- Frequency (Hz)
New services
Three new services are available for newer Redfish devices:
- Power Subsystem — power supply redundancy status and total capacity
- Environment — aggregate system power consumption
- Power supply — individual PSU details like manufacturer, model, and capacity
These services appear automatically during discovery on supported devices. If your devices were already monitored before this update, nothing changes.
