PSU Energy - AC - SDIA - System
What it does
It estimates the total system energy consumption (AC Power) based on the SDIA linear model, which takes TDP, CPU-Chips and Utilization as input variables.
The formula works as follows:
(CPU-Chips * TDP * Utilization) / 0.65
0.65 is the coefficient assumed to be the amount the CPU contributes to the total energy consumption of a non-GPU server.
The provider must be configured in the
config.yml. Please see Configuration →
for further info.
config.yml file also the CpuUtilizationProcfsSystemProvider must be activated
for the PsuEnergyAcSdiaSystemProvider to work.
- Takes no arguments
The provider cannot be run directly, it only works in conjunction with a run of the Green Metrics Tool.
The provider reads the
from the CpuUtilizationProcfsSystemProvider in order to keep overhead low and
not to double query the utilization from the system.
Since this provider should not be run directly there it has no direct output.
The resulting data however is the wattage for the whole system (AC Power) in Watts.
This value has the same granularity as the one configured in the
config.yml for the
Any errors are printed to Stderr.
