Kepler (Kubernetes-based Efficient Power Level Exporter) uses eBPF to probe performance counters and other system stats, use ML models to estimate workload energy consumption based on these stats, and exports them as Prometheus metrics

panic when using pre-trained model #1476

Open lianhao opened 2 months ago

lianhao commented 2 months ago

What happened?

When running the kepler in K8S with the pretrained model to estimate the process power, kepler pod just go panics after launch.

The models are trained by following kepler model server tekton training process, using the complete run.

Kepler container goes into error just after it started:

There are some errors in kepler-estimator container too:

What did you expect to happen?

Kepler should be run without any panics

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

run kepler with the kepler deployment configurations below.

Anything else we need to know?

It seems the trained power model using the CPU time metric exported by Kepler before v0.7 (bpf_cpu_time_us); however, the estimation is called by the new Kepler (with bpf_cpu_time_ms). You may have to retrain the power model with new Kepler version.
