(synopsis "Measure system power consumption")
(description
"Powerstat measures and reports your computer's power consumption in real
time. On mobile PCs, it uses ACPI battery information to measure the power
drain of the entire system.
Powerstat can also report @acronym{RAPL, Running Average Power Limit} power
domain measurements. These are available only on some hardware such as Intel
Sandybridge and newer, and cover only part of the machine's components such as
CPU, DRAM, and graphics. However, they provide accurate and immediate readings
and don't require a battery at all.
The output is like @command{vmstat} but also shows power consumption statistics:
at the end of a run, @command{powerstat} will calculate the average, standard
deviation, and minimum and maximum values. It can show a nice histogram too.")
