New Feature: Check VMC certificate #1414
Description
It would be nice to be able to use blackbox_exporter to monitor for expiration of VMC certificates.
The process is something like a cross between a DNS probe and an HTTP fetch, where you use DNS to find out the URL of the VMC certificate, then you fetch the VMC certificate. We would need to parse that certificate, and then set prometheus counters like probe_ssl_earliest_cert_expiry with the number of seconds left.
My company would be willing to implement this; is there interest in a PR?
