Use Case

Running Average Power Limit (RAPL) allows measuring the energy consumption of CPU and DRAM on x64 CPUs.
Linux implements access to these values over the file system using the Power Capping Framework.

RAPL is known to be highly correlated to the actual energy consumption of the server and thus a good metric for gauging energy/power consumption in production without additional hardware.

Expected behavior

Facilitate reading the energy consumption across all RAPL domains through a new input plugin.
Optional: Derive average power consumption between measurements.

Actual behavior

Not implemented.
