Monitoring intermediate cert expiry using prometheus

Hi Team,

We are using Prometheus to monitor the vault and found that there is no metrics exported by vault to monitor cert expiry.

we managed to monitoring leaf level cert using blackbox-exporter, but facing issue with monitoring of intermediate CA.

What’s the best way to monitor intermediate CA certs using Prometheus.

Thanks.

That is not really a Vault related question is it?
