With EXCLUDE_SWAPPER_PROCESS enabled, kepler reports VM power more than actually consumed by VM

[sthaha]

Setup

Deploy latest kepler with EXCLUDE_SWAPPER_PROCESS set to true on a baremetal

kepler-1  | I1105 04:34:34.940824  939885 config.go:267] EXCLUDE_SWAPPER_PROCESS: true

Test

• Compare increase in node-exporter-rapl vs kepler_node_package vs kepler_vm_package

Note that the

• green is rate(node_rapl_package_joules_total{job="metal-node-exporter"}[${rate}s])
• red is sum(rate(kepler_node_package_joules_total{job="metal"}[${rate}s]))
• blue is sum(rate(kepler_vm_package_joules_total{job="metal"}[${rate}s]))

Blue (which is fraction of the total power) is reported way higher than the increase in kepler-node-package watts
In the above example, the increase in watts reported by kepler_node_package is as below

It raise from 18.0 to 29.2 =~ 12 W

While kepler_vm_package watts is as follows

It raises from 0.9 to a max of 26.9 W

Additionally, `
abs(
sum(rate(kepler_process_package_joules_total{job="metal"}[20s])) -
sum(rate(kepler_node_package_joules_total{job="metal"}[20s]))
)

 shows that the difference is sometime as high as 6W
