kube-state-metrics - invalid metric type "info" #31

Closed sebastiangaiser closed 5 months ago

sebastiangaiser commented 5 months ago

Hey,

we upgraded kube-state-metrics to v2.11.0. Since then we get the error message invalid metric type "info" for scraping kube-state-metrics. With v2.10.1 everything was working fine.

We already discovered that https://github.com/fluxcd/flux2-monitoring-example/issues/14 shows a similar problem but as written it was working for us in the prio version.

Additionally we found: Info metrics are used to expose textual information which SHOULD NOT change during process lifetime. Common examples are an application's version, revision control commit, and the version of a compiler. source

I'm experiencing the same problem upgrading kube-prometheus-stack to 57.2.0 which will obviously upgrade kube-state-metrics to the corresponding version.

Most likely related to: https://github.com/kubernetes/kube-state-metrics/issues/1973#issuecomment-2024736652 The fix seems to be merged: https://github.com/kubernetes/kube-state-metrics/pull/2270

Same error after the same upgrade.

Is there a mitigation recommended? We can remove ksm configuration or rollback to previous version of KSM.

This prevents the whole kube-state-metrics to be operational 🤔.

Upgrading kube-state-metrics to '2.12.0' solves this issue.
