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

Metric kepler_container_bpf_net_tx_irq_total showing as zero #1270

Open emoek opened 7 months ago

emoek commented 7 months ago

What happened?

The metric "kepler_container_bpf_net_tx_irq_total" only shows "zero" for all containers and pods.

What did you expect to happen?

I expected non-zero values similarly to the network transmit metric provided by cAdvisor as visible in the figure. image

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

I guess just install the below specified Helm version of Kepler and test it out.

Anything else we need to know?

The receive metrics net_rx_irq works as expected, or more precisely everything else works as expected. image

@emoek can you provide more info? what is the kepler image you are using, what is the OS platform, do you have access to the kepler container logs?

emoek commented 7 months ago

I only have limited access to the cluster as its a private cluster but I will try to get as many informations as I can get. In the image you can see the log output the last time I had access to them. It seems to be that the Kepler version is "c1cae95" and the kernel version "5.1" on an Debian/Ubuntu server. image
