days_until_first_cert_expiring can be very useful as a reminder to rotate the certs.

There're also some TLS related stattistics on the listener: https://www.envoyproxy.io/docs/envoy/latest/configuration/listeners/stats#tls-statistics

You can follow the Gateway Observability task to retrieve these metrics.
