SSL monitoring
SSL monitors connect to your host and port (for example exemplar.dev:443 on a set check interval), validate the certificate, and surface expiry, issuer, subject, and serial details. The timeline and check history show repeated successful checks with days-to-expire on each row so you can audit TLS health over time.

Example: SSL monitor with expiry date, issuer/subject, and hourly check history.
