cpupower: rapl monitor - shows the used power consumption in uj for each rapl domain
This CPU power monitor shows the power consumption
as exposed by the powercap subsystem, cmp with:
Documentation/power/powercap/powercap.rst
cpupower monitor -m RAPL

Unfortunately RAPL domains cannot be directly mapped to the corresponding
CPU socket/package, core it belongs to.
Not sure this is possible at all with the current data exposed from the
kernel.
Still it can be worthful information for developers trying to optimize
power consumption of workloads or their system in general.
