Hi there, I encountered the same issue, and I don't think the expr query work as expected. I think the `apiserver_client_certificate_expiration_seconds_count{job="apiserver"}
0 and on(job)` part is not correct. As the result, the value of the whole query is not decreasing but monotonically increasing. I know it should be fixed in https://github.com/kubernetes-monitoring/kubernetes-mixin
As the workaround this worked to me:
histogram_quantile(0.01, sum by (job, le) (rate(apiserver_client_certificate_expiration_seconds_bucket{job="apiserver"}[5m])))
and on (job) apiserver_client_certificate_expiration_seconds_count{job="apiserver"} > 0

Describe the bug a clear and concise description of what the bug is.
Kube-prometheus-stack helm chart is installed in an AKS cluster, but there is an issue with "KubeClientCertificateExpiration" alert, which shows wrong values for the expression output. Validated the "kube-apiserver" certificate expiration based on the output by converting the output value which is in seconds to days, but its not matching the alerts.
Version: -kube-prometheus-stack-45.8.1 v0.63.0
