Alternatively one could compare to `-604800` instead of 0 in order to include the certs having expired in the past 7 days. This limits alerting noise due to certificates that are not replaced in-place on rotation, for example the serving-certs in openshift-kube-controller-manager that accumulate to great numbers over the years.
