With k3s, is it normal that the Kubelet SLI metrics endpoint is not found?

[gerardnico]

Hallo,

Scraping:

• the SLI metrics of API server at :6443/metrics/slis works
• Kubelet at :10250/metrics also work.
• but not the SLI metrics of Kubelet at :10250/metrics/slis.

I get a 404 Not Found specifically:

Error scraping target: server returned HTTP status 404 Not Found

Is this normal with k3s or do I need to enable them via a feature gate?

Thanks

Context:

• this scraping targets were installed with kube-prometheus
• I can't find any relevant documentation over Kubelet SLI metrics on https://docs.k3s.io/

What version are you using? There appears to be a bug in the kubelet SLI endpoint that may affect whatever version you're on:

• do not install handler for '/metrics/slis' endpoint using sync.Once kubernetes/kubernetes#128430

Ah thank you. I didn't go in the bug route because I didn't see also a controller-manager or scheduler which seems normal??

I need to install the v1.32 it seems.

The version:

k3s -v

k3s version v1.31.0+k3s1 (34be6d96)
go version go1.22.5

Thanks

Yep you're several months behind on patch releases.
