Two Kepler deployed on same machine report different power usage

[vprashar2929]

What happened?

When two instance of same Kepler versions are deployed on same BM machine and then stress is applied to the machine both Kepler versions report power values that are different from each other.

Attaching below screenshot for reference:

What did you expect to happen?

Since there are no code changes and both Kepler instances are using the same Kepler version ideally they should report the same power values

How can we reproduce it (as minimally and precisely as possible)?

1. Deploy two versions of Kepler using dev compose manifests
2. Compare below Kepler dev vs latest metrics:

sum( rate( kepler_process_package_joules_total{ job="dev", }[20s] ) )
sum( rate( kepler_process_package_joules_total{ job="latest", }[20s] ) )

sum( rate( kepler_process_core_joules_total{ job="dev", }[20s] ) )
sum( rate( kepler_process_core_joules_total{ job="latest", }[20s] ) )

sum( rate( kepler_process_dram_joules_total{ job="dev", }[20s] ) )
sum( rate( kepler_process_dram_joules_total{ job="latest", }[20s] ) )

sum( rate( kepler_process_other_joules_total{ job="dev", }[20s] ) )
sum( rate( kepler_process_other_joules_total{ job="latest", }[20s] ) )
