Hi There, I have several older kubernetes clusters and I need a way to alert on the kubelet/kubeadm certs before they expire.
>From the kubernetes-nodes job we get several metrics: apiserver_client_certificate_expiration_seconds_count apiserver_client_certificate_expiration_seconds_sum apiserver_client_certificate_expiration_seconds_bucket But I am not really clear on how to use these values to determine either a countdown to expiry or the actual expiration date. The bucket metrics have an "le" label but not sure what that means. Thanks, Kevin -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
