Is your feature request related to a problem? Please describe.
Not applicable

Describe the solution you'd like
It would be nice to have sensor for CPU load in W (in best case to have three sensors, one for 1 minute aggregation second for 5 minutes and third for 15 minutes as is usual for that stat)

Use Case or Why Do You Want This?
Describe a specific scenario where this feature would be helpful or explain why you think it's necessary.

I looked into this and..

CPU load average sensors can be implemented in Unraid system. These sensors can show the standard 1-minute, 5-minute, and 15-minute load averages that Unix-like systems track.

A few important notes:

• The load averages will be presented as dimensionless numbers (not watts), which is the standard way they are reported
• A load average of 1.0 means full utilization of one CPU core
• For a system with 4 CPU cores, a load of 4.0 would indicate full utilization
• Load numbers can go above the CPU core count if there are processes waiting for CPU time

The three new sensors will be created:

• CPU Load (1m): Shows the average system load over the last minute
• CPU Load (5m): Shows the average system load over the last 5 minutes
• CPU Load (15m): Shows the average system load over the last 15 minutes

While you mentioned wanting power consumption in watts, accurately measuring CPU power usage would require additional hardware monitoring capabilities that aren't consistently available across Unraid systems. The load averages provide a reliable way to monitor the system's CPU demand over time.

Oh, my fault regarding that units, probably I've got wrong information regarding that, so that CPU load average sensors will be right thing 😊
